[PATCH] Do not call fetch() when we have it.
Currently pull() calls fetch() without checking whether we have the wanted object but all of the existing fetch() implementations perform this check and return success themselves. This patch moves the check to the caller. I will be sending a trivial git-local-pull which depends on this in the next message.
