I do not think this matters much in practice.  If you have tons of refs on
_your_ side to matter, some of them would be tags that are known to both
ends.  The only case it really is troublesome is when the sender does not
know _any_ of the refs the receiver presented to it.

In the illustration in the message you are responding to, if the commit A
was tagged at the shared repository when two developers cloned, it does
not matter if C is unknown to the second pusher.

So a potential improvement might be to ask for "tellme-more" only if we do
not know any of the refs the receiver showed us; my patch does it if there
is at least one unknown instead.
