I don't like the automatic prune. What if someone has other objects in
there which shouldn't be pruned? Making git svn dcommit doing the prune
would be at least suprising, because how is one supposed to know that
doing a commit into svn will prune all your precious objects?
Sure, I can unterstand from where you are coming from, but I'd prefere
if this could be specified on a case by case basis, e.g. from the
cmdline or as a config option.
