I think the intent of a95ce124 (maintenance: replace run_auto_gc(),
2020-09-17) was to update all codepaths that run "git gc --auto" to
instead run "git maintenance --auto", but only updated the ones that
used to call run_auto_gc().  The codepath Patrick found runs "git gc
--auto" without using run_auto_gc() and was left behind when the
others were converted.

So why do this?  I think "To follow through a95ce124 started" would
probably be a good enough reason, if a reader is on board with what
a95ce124 wanted to do.

Do we have a handy reference that compares "gc --auto" and
"maintenance --auto"?  Are they essentially the same thing these
days?  What are the things that is done by one but not by the other?

THanks.
