Well, the only thing we need to do in fetching between two
repositories that are already identical should be to compare
ls-remote output from both ends and immediately declare victory,
and it is unacceptable for such an obvious no-op to take 30
seconds.  At this point it really is the shell loop that is
killing us.

I only really made the changes so I could try your improvements to
fetch out - if they aren't necessary because you're making it even
faster then I really don't have much cause to complain.

I've applied your fixes to jc/fetch topic and merged it back to
'pu'.  Thanks.
