Heh.  That is a really good idea.  I've been thinking about doing
some automatic generational style GC type repacking controls in
git-gui, and doing them when git-gui is sitting idle and has not
been used in the past couple of minutes.

This is along the same vein of thought.  I like it.  Often it
takes me a while to come up with a good commit message even if
I am using command line commit.

But git-rebase/git-am can cause a huge number of objects to be
created, especially if you are pushing a large stack of patches
around.  So it may still be a good idea to trigger `gc --auto`
at the end of those operations.

Here's a better thought:

If we are pushing somewhere, and the push size is "large-ish" and
we aren't pushing a thin pack (its currently considered not nice
to the remote end so it doesn't happen by default) and the objects
we are packing are mostly all loose maybe we should also save a
copy of that packfile locally, then prune *only* those loose objects
back.

Not every git user pushes their work.  But many do.  And those
that push usually will do so in bursts, are already expecting to
wait for the network latency, and usually are pushing the majority
of the things that are loose.  Such users will probably never see
the `gc --auto` trip in places like commit/am/merge as they would
already be clearing their ODB with the push.
