I'm a little hesitant to suggest this as I'm not sure how available I
could be for mentoring and don't view myself as a good mentor, but
another project idea which has lots of sub-pieces and thus could show
progress and be useful even if not everything is completed:

Consistency of sequencer commands:
* The suggestion to fix an interrupted rebase-i or cherry-pick due to
a commit that became empty via 'git reset HEAD' (in builtin/commit.c)
instead of 'git rebase --skip' or 'git cherry-pick --skip' ranges from
annoying to confusing.  (Especially since other interrupted am's and
rebases both point to am/rebase --skip.).  Note that 'git cherry-pick
--skip' is not yet implemented, so that would have to be added first.
* There are a handful of flags that am-based rebases support that are
not available to interactive/merge-based rebases; it'd be nice to
implement them for the interactive machinery.  (There are also
numerous flags that only the interactive machinery supports that are
unavailable to am-based rebases, but I don't care; I want to deprecate
am-based rebases.)
  * --ignore-whitespace (transliterate to -Xignore-space-change?)
  * --whitespace=...
  * --committer-date-is-author-date/--ignore-date
  * -C4

[There's also some empty handling (from "Behavioral Differences" in
Documentation/git-rebase.txt) that would be nice to address, though
that might be contentious and I might try to tackle that piece before
GSoC gets rolling...]

Bonus: Make a flag to allow rebase to rewrite commit messages that
refer to older commits that were also rebased.  (i.e. if rebasing
commits A and B, and commit B says "This reverts commit <sha-of-A>,
then rewritten B's commit message should say "This reverts commit
<sha-of-rewritten-A".)  Do this for both sha1sums and sha1sum
abbreviations in commit messages.
