Well, my goal was to try to stick to the output of the official
commands, figuring that this is essentially the standard to go by.  My
understanding is that subtle problems with character encodings and
such were found in past conversation efforts.  If unusual characters
are being modified by the conversion program I want to avoid the
verification program making the same mistake and therefore obscuring
the problem.

That said, spawning git several million times is looking to be REALLY
slow, so I think I might bite the bullet and use a library.  It seems
like pygit2 is designed to use unicode for everything.

And of course the risk that pygit2/etc has bugs really isn't
necessarily greater than the risk that my own stuff has bugs (though
knowing my intended use I can probably minimize the ones that count -
the logic really is simple).

The repository contains currently what should be a working
implementation (though it doesn't write the final list out to disk).
It is just WAY too slow to run (hence the command line parameter to
limit the number of commits examined).

Pretty busy for a few days, but I'll convert the git spawning and
output parsing to pygit2 calls.  As an added bonus I don't have to
deal with the fact that git just LOVES to mangle its output to be
pleasing to eyes and less so to robots.
