    Stop Windows PuTTY becoming unresponsive if server floods us.
    
    This was an old bug, fixed around 0.59, which apparently regressed
    when I rewrote the main event loop using the toplevel_callback
    mechanism.
    
    Investigation just now suggests that it has to do with my faulty
    assumption that Windows PeekMessage would deliver messages in its
    message queue in FIFO order (i.e. that the thing calling itself a
    message queue is actually a _queue_). In fact my WM_NETEVENT seems to
    like to jump the queue, so that once a steady stream of them starts
    arriving, we never do anything else in the main event loop (except
    deal with handles).
    
    Worked around in a simple and slightly bodgy way, namely, we don't
    stop looping on PeekMessage and run our toplevel callbacks until we've
    either run out of messages completely or else seen at least one that
    _isn't_ a WM_NETEVENT. That way we should reliably interleave NETEVENT
    processing with processing of other stuff.

    Don't output negative numbers in the ESC[13t report.
    
    A minus sign is illegal at that position in a control sequence, so if
    ESC[13t should report something like ESC[3;-123;234t then we won't
    accept it as input. Switch to printing the numbers as unsigned, so
    that negative window coordinates are output as their 32-bit two's
    complement; experimentation suggests that PuTTY does accept that on
    input.

    Stop misidentifying git commit hashes as PuTTY releases.
    
    The Wishlist page currently contains a section with the heading 'Fixed
    in release 7d97c2a8fdb745905fd61a9ce4abbf822e167cef', because I
    entered that commit id in the Fixed-in header for spew-lockup-2.
    
    git commit hashes in Fixed-in should be informational only - they
    should show up in the individual bug pages, but play no part in the
    formatting of the main Wishlist page.

    Reverse-order the release sections on the wishlist page.
    
    It's becoming far too silly to have the most important parts of the
    page - which bugs are fixed in the latest release, or still exist in
    the latest release but are fixed in the snapshots - be _half way down_
    the page, between all the historical info about very old releases and
    the still-unfixed wishlist section.
    
    So I've reordered those sections to put the latest releases at the top
    and the old ones down at the bottom. This wasn't just a question of
    prefixing 'reverse' to the 'sort' in the main loop, because the
    'Broken and fixed between' section was implemented by remembering the
    last thing we saw going round the loop, so I also had to move that
    around and swap $oldclass with $class in its code.

    New build script for testing purposes.
    
    'bob -s Buildscr.test' builds Halibut, runs it over inputs/test.but to
    produce all the supported output formats, and delivers them all into
    the output directory. Including Windows HTML Help, for which it has to
    do a special run of the HTML back end with extra options and then get
    a Windows box to run hhc (hence this having to be a Buildscr).

    Make HTML Help files display a font-size change button on the toolbar.
    
    I had no idea that was a thing HTML Help could do at all, let alone
    that .chm files could enable or disable it via a flag! But Tino
    Reichardt sent in a patch which sets one extra bit in a flags word in
    the .hhp file, and despite 'chmspec' not mentioning that bit at all,
    it does indeed seem to do something useful.

    Get rid of the bool return value from sign_exp().
    
    I've decided it wasn't the right way to handle IEEE overflow after
    all, because it set the 'done' flag in the BaseOutputGenerator main
    loop which then did unhelpful post-rounding processing on the
    resulting formatter. Instead, formatters in the overflow state now
    mark themselves as complete in a way that's _separate_ from that
    'done' flag, and not checked by anything except the code that checks
    the final termination condition.
    
    I'd reused the same flag for %f formatting of exponents smaller than
    the precision, which was lazy; that's obviously better done with the
    same min_exp mechanism that BaseFormatter uses. Added some test cases
    that failed before.

    More sophisticated calculation of exponent in base output.
    
    The previous approach of just taking floor_log of the integer at the
    end of an interval was not quite robust, because some of those
    interval-end integers are implicitly 'plus or minus epsilon', and the
    minus-epsilon case can make a difference. Also, terminating the
    exponent-finding loop once the two ends of the interval differ by less
    than a factor of ebase turned out to be not quite robust: in cases
    where it's possible to round up to the next exponent and the rules for
    doing so can change depending on exponent, it was occasionally
    possible to find a case which finished the exponent loop with a range
    of three rather than two possible exponents.
    
    So instead, we now have a more rigorous function for computing an
    exponent from an integer plus an 'is this exact' flag, and we
    terminate the exponent loop once the two ends of the interval yield
    return values from that function differing by at most one.
    
    In the course of this, I've also factored out the translation of
    user-provided rounding modes into non-sign-dependent ones (e.g. 'round
    up' becomes either round toward zero or round toward infinity once the
    sign is known), since it now has to be called during the tentative
    exponent calculation as well as once the exponent loop actually
    terminates.

    Fix identification of cross-exponent rounding boundaries.
    
    In cases near an exponent boundary, where we're simultaneously running
    two formatters with different exponents, the formatter for the higher
    exponent typically miscomputes the low end of its catchment interval.
    (Because that computation is based on _its_ idea of the distance
    between representable outputs, and in case of a disagreement the lower
    formatter's idea is right. IEEE round-up is an example of this.)
    
    So I've now arranged that we notice that situation, and when we see
    it, the upper formatter discards its own idea of the rounding boundary
    and defers to the lower's one.

    New feature: 'tentative output'.
    
    This mitigates at least some of the annoying situations in which
    spigot can't compute an answer due to it being _too easy_; the example
    I've used throughout the docs is sin(asin(0.12345)). Previously, we
    printed 0.1234 and then dithered forever failing to compute the 5; now
    we print the 5 in a way that clearly marks it as 'not completely sure
    of this but it looks likely', and retract it later if better
    information comes along.
    
    In the course of documenting this, I've completely rewritten the
    hazards section of the documentation, so that it categorises exactness
    hazards into various subtypes and explains which one tentative output
    applies to. Also I've done something disgusting in Makefile.am to pipe
    Halibut's HTML output through a Perl one-liner, in order to go beyond
    Halibut's limitations and get red text in a few of the example
    terminal session snippets.
    
    There's a new option --tentative to turn tentative output on and off
    (and, like colour ls, it has a default third state 'auto' which
    applies only when outputting to a terminal device), and also an
    undocumented --tentative-test option intended for use by the test
    suite.

    With tentative output set to auto, failing to retrieve one of the
    terminal control strings we need just causes it to be quietly turned
    off. But if the user specifically says they _definitely_ want it, and
    we don't manage to enable it, we should explain why we can't.
    
    The error isn't fatal; spigot will still continue without tentative
    output after printing it.

    Handle the special case of exp(0) sensibly.
    
    Prior to this change, an input value of zero was getting all the way
    into the ExpRational class, which would then return all-zero spigot
    matrices forever, which is not a useful behaviour at all.
    
    This didn't cause any obvious problems with computing exp(0) itself,
    but other more complicated expressions would fail, such as 0*exp(0)-k
    for rational k. I initially noticed this bug by means of W(0.1234)
    failing an assertion, which turned out to be because xex_constructor()
    had built an expression of just that form. Added both of those as
    regression tests.

    Fix a compile warning on ARM.
    
    Aapo Rantalainen points out that comparing 'char c' against zero gives
    rise to gcc's "comparison is always false" warning, which escalates to
    an error under -Werror.
    
    This is one of those situations where the warning is doing more harm
    than good, but here's a rephrasing which casts to unsigned so that
    both negative numbers and positive out-of-range ones can be caught by
    the same comparison.

    Fix clang warning from passing string literals to tigetstr.
    
    Annoying to have to, since obviously tigetstr _should_ normally expect
    a string literal, but it's from the Dawn Of Time and hence declared to
    take a char * rather than a const char *, so what can you do.
    
    (Admittedly this is a somewhat overengineered fix, but.)

    Fix a clang warning about switching on an enum.
    
    In this case, there's an obviously good reason why not all values of
    the enum appear as case labels in the switch, but clang didn't spot
    that. With this fix, spigot builds without warnings on OS X.

    Add Tracks to the automake makefile's "install" target.
    
    Each game's .R file should append the binary to $(GAMES) in both the
    'am' and 'gtk' makefiles, but presumably due to copy-and-paste from an
    out-of-date version, tracks.R only did 'gtk'.
    
    Also clarified CHECKLST.txt in the hope that I won't miss that again.

    Fix the Python spigot interface.
    
    I forgot to update it when I completely rewrote the base output
    system. This change makes it compile again, and run test.py
    successfully.

    Fix another assertion failure in BaseOutputGenerator.
    
    A test case I stumbled on just now points out that it's possible to
    accidentally generate three parallel formatters, in the case where the
    lower of two exponents generates two and then the higher exponent
    (because it's ignoring its own lower bound) generates a third one.
    
    I think in that situation it's correct to just discard the spurious
    higher-exponent formatter. Added a special case for that, and a
    regression test.
