[PATCH] Don't allocate too much memory in quote_ref_url

[PATCH] Don't allocate too much memory in quote_ref_url

[Mike Hommey]

In c13b263, http_fetch_ref got "refs/" included in the ref passed to it,
which, incidentally, makes the allocation in quote_ref_url too big, now.

I noticed this when rebasing some of my private branches onto current
master. I had a commit similar to c13b263 that ended up conflicting,
and after conflict resolving, this is all that was left, which is
an obvious change that was lacking there.
