     YES! yikes.

This is about the best argument put forth so far for not automatically
running git-gc. Personally, I think git-gc should not remove unreferenced
objects without --prune (but I haven't done anything about it). But even
if git-gc was modified in this way, an occasional git-gc --prune would
still be necessary to remove all of the unreferenced and dangling objects
safely with a human thinking about the shared repo implications (unless
shared repo handling is modified).
