If cherry-pick, revert or 'rebase -i' edit the commit message then they
fork 'git commit' so gc --auto will be run there anyway. I wonder if it
would be better to call 'gc --auto' from sequencer.c at the end of a
string of successful picks, that would cover cherry-pick, 'rebase -iu'
and revert. With 'rebase -i' it might be nice to avoid calling 'gc
--auto' until the very end, rather than every time we stop for an edit
but that is probably more trouble than it is worth.
