This is a lot of change, and in some ways I think it is making things
better overall. However, the simplest fix for this is basically to move
the setting of GIT_EDITOR down to after we prepare the index.

Jun Hao (cc'd) has been preparing a series for this based on the
Bloomberg git hackday a few weeks ago, but it hasn't been sent to the
list yet.

Commits are here:

  https://github.com/bloomberg/git/compare/commit-patch-allow-hunk-editing

if you care to look. I'm not sure which solution is technically
superior, but it's worth considering both.

I regret not encouraging Jun to post to the list sooner, as we might
have avoided some duplicated effort. But that's a sunk cost, and we
should pick up whichever is the best for the project.
