[PATCH] git verify-pack -vs

According to git help verify-pack, when --stat-only and --verbose are 
used together the "list of objects is also shown." But in fact it is 
not; `git verify-pack -sv` has the same behavior as `git verify-pack -s`
It seems like a trivial mistake in verify-pack.c (the verbose behavior 
is triggered with !stat_only) so here is a patch that makes the behavior 
fit the manual's description.
