    bugs2html.py: factor out a small GitRepo class.
    
    This isn't much of a wrapper on just invoking git in a subprocess, but
    it at least lets me do subprocess.check_output()-like calls, except
    that I can provide input if necessary, and it arranges to put plenty
    of diagnostic details in the exception traceback (including both
    standard error and the full command line) if anything goes wrong.

    bugs2html.py: new git-ancestry-based Fixed-In inference.
    
    This replaces the previous system of relating each released version to
    an svn revision, which was fragile, annoying to maintain,
    fundamentally inelegant given that we don't even _use_ svn any more,
    and limited what the commit graph in the git repository might be able
    to look like without confusing the script. Now we do the much more
    conceptually clean thing of simply asking: is the git tag
    corresponding to the release a descendant of any git commit listed as
    having fixed the bug?
    
    Combined with the large number of git commits I retrospectively
    inserted in lots of old bug records the other day, this version of the
    script still generates bit-identical output to the Perl version -
    every version number inferred by the new technique is the same as the
    one that was inferred by the old one.
    
    One side effect is that bugs2html.py now needs to access the main
    PuTTY repository (you can't test git commit hashes for ancestorhood
    without looking at a copy of the whole repo), which makes the script
    run considerably more slowly in its default mode, because it will
    clone the repo from scratch in a temporary directory. However, you can
    provide a command-line option pointing to an existing checkout, and
    then it will run much faster, by simply doing a 'git fetch' to update
    a set of local mirroring refs. (And those refs live in a special
    namespace 'refs/putty-wishlist', so they shouldn't even interfere with
    any ordinary branches or tags in the same checkout.)

    bugs2html.py: completely remove the old release_versions map!
    
    The new git ancestry system removes the need to manually describe the
    branching structure surrounding past releases, because bugs2html.py
    can now directly read the record of the branching structure from the
    git repository itself. As a result, the only remaining need for a list
    of release versions was in a few places where we just have to iterate
    over all the releases in existence, or generate a different identifier
    or piece of wording depending on whether a given version number refers
    to a released or pre-release version. And those can be done using a
    much simpler map of versions to boolean 'is this a pre-release?' flag,
    which in turn can be auto-generated by scanning the list of git refs.
    
    This means that in future I'll have to be consistent about naming
    pre-release branches, but since git makes branch-renaming extremely
    easy, that shouldn't be a problem.
