Yes, it probably should. Can you submit a patch describing the behavior
where you think it ought to go?

I think it's an interesting avenue to pursue, though I would worry a
little about robustness. I like the fact that after rebasing, the
commits have done a complete git->cvs->git loop and look identical, so I
am sure everything made it through intact. But perhaps I'm just being
paranoid.

As an alternate idea, why not try to have the CVS commit contain all
information necessary to create a particular git commit. IOW, describe
all of the data that goes into the commit hash as textual comments in
the CVS commit (committer name/time, author name/time). And then
theoretically git-cvsimport can reconstruct the exact same commits
again, and your git->cvs->git merge really _will_ be a fastforward.

I've been in the same boat, and just used the rebase trick I described.
Of course it was a very tiny project, so I didn't mind losing some of
the full power of git.
