Hmph, is it an improvement to warn() when the user does not mind
cloning a shallow repository?
$ git clone --depth=3 $URL clone-1
$ git clone file://$(pwd)/clone-1 clone-2
would give us clone-2 that is just as functional as clone-1 is, no?
clone-1 may be missing objects that is needed far into the past, and
clone-2 would lack the same set of objects as clone-1 does, but a
user who is happily using clone-1 would be happy with clone-2 the
same way, no?

Stopping early before calling get_pack() would significantly reduce
the overhead, which is good.

The same question on the wisdom of warning here.

OK, so, this is the equivalent of the above for protocol-v2? The
same comments apply, then.

OK. Also without "--no-reject-shallow" option, the command would
successfully clone from the shallow-repo, I presume?
The changes look more-or-less good to me, except for the "warning()"
bit, which I do not think is a good idea.
