    Python: mark the PRINTF_* flag family as private.
    
    They're not intended as part of the external API that client code will
    use; they're an internal implementation detail between the Python and
    C halves of the spigot module itself. So they should be named with the
    usual underscore prefix, to reflect that.

    Python __format__: fix mishandling of the '0' flag.
    
    When no pure-alignment specifier (i.e. one of the <^>= chars) was
    given, I was setting the alignment to the usual default of '>', rather
    than leaving it at None so that the default could be decided later on
    once we knew if we'd got the convenience '0' flag. So '0' failed to
    set the alignment to '='.

    Stop trying to mimic Python's default float precision.
    
    Turns out Python 2 and 3 disagree on it. In fact, P3 doesn't even seem
    to be choosing a fixed number of digits, in that "{}".format(4.0/3.0)
    and "{}".format(math.pi) come out at different lengths. I suspect it's
    doing something clever in IEEE terms, outputting just enough digits to
    make the value unambiguous. But that's certainly not something I want
    to mimic in spigot, because it's a meaningless concept anyway. So I
    might as well just abandon the attempt to match Python floats, and
    pick my own precision. 20 seems like a good number of digits - it's
    just enough to make the point that this is better than floats :-)

    Python: add some missing exception handlers.
    
    Functions that retrieve data from an already-formatting spigot were
    not prepared for it to throw a late-breaking spigot_error due to
    having belatedly discovered a domain error, so they weren't catching
    the C++ exception and converting it correctly into a Python one.

    Python: separate test from demo programs.
    
    The previous test.py is gone, because it was mostly a demo, slightly a
    test, and not very organised.
    
    Now we have testsuite.py which is a fully automated set of Python unit
    tests (much more thorough), and the demo.py which is a nicely
    commented quick demonstration of some spigot functionality (and
    contains the more demo-like parts of the old test.py).
