-s would be a lot safer to use if repack -a -d (as used by git-gc) was smarter.
-a -d has the nasty side effect of doing what it seems only prune is intended
to do... that is to remove unreferenced objects.

-s usage currently has to be very well thought out, unless you're just using it
for a short-lived temporary branch. If this unintended pruning could be avoided
then an average user could go about their merry business repacking and git-gc'ing
without a care, and only when doing a git-gc --prune would they need to do
something special.
