Given the CGit and Git are both GPLv2, we could always just take
strbuf.[ch] and the argv-array bits from git.git and copy them into
CGit. Likewise the test suite could switch to using Sharness with very
So I don't think the recent changes towards using more bits of Git
actually have too much impact here.

I won't have time to do this in the near future.
The first step in this direction may actually be useful even if we stick
with embedding libgit.a. Re-writing the commit graph drawing ourselves
could allow prettier output than the ASCII we inherit from Git.
