Subject: [PATCH] revert & cherry-pick: run git gc --auto

Expand on the work started in 095c741edd ("commit: run git gc --auto
just before the post-commit hook", 2018-02-28) to run "gc --auto" in
more commands where new objects can be created.

The notably missing commands are now "rebase" and "stash". Both are
being rewritten in C, so any use of "gc --auto" there can wait for
that.

After reading the "Users are encouraged to run this task..." paragraph
in the git-gc manpage I was wondering if due to gc --auto all over the
place now (including recently in git-commit with a patch of mine) if
we shouldn't change that advice.

I'm meaning to send some doc changes to git-gc.txt, but in the
meantime let's address this low-hanging fruit of running gc --auto
when we revert or cherry-pick commits, which can like git-commit
create a significant amount of loose objects.
