[PATCH v2 0/2] Fix protocol v2 tag following with CLI refspec

> Test t5702-protocol-v2.sh doesn't pass with this patch.

Good catch - I've fixed that.

It's true that there is now a performance drop. My instinctive reaction
is to be conservative and preserve the existing behavior, but I'll see
what others on this list think.

It's worth nothing that with ref-in-want (for example, in your latest
series [1]) we might be able to restore performance, because the server
can send refs/tags/X with the packfile instead of sending all
refs/tags/X refs initially to the client.
