Subject: [PATCH] fetch-pack: check for shallow if depth given
When a repository is first fetched as a shallow clone, either by
git-clone or by fetching into an empty repo, the server's capabilities
are not currently consulted. The client will send shallow requests even
if the server does not understand them, and the resulting error may be
unhelpful to the user. This change pre-emptively checks so we can exit
with a helpful error if necessary.
