I'll make sure to add one :)

Yes and no.  Remote-curl will run this when trying to establish a
stateless-connection.  If the response is v2 then this is a capability
list and not refs.  So the capabilities will be dumped to the client and
they will be able to request the refs themselves at a later point.  The
comment here is just misleading, so i'll make sure to fix it.

Always making new code have higher standards than the existing code ;)
Haha, I'll add a simple comment explaining it.

I'll add a comment that its used as a READFUNCTION callback for curl and
that it tries to copy over a packet-line at a time.

No its just that Curl only requests a set about of data at a time so you
need to be able to buffer the data that can't be read yet.

Yeah i can go ahead and do this.  Just note that the v1 path uses logic
identical to this so it would be a problem there.

Sounds good.

I do see the draw for wanting this.  I think a change like this requires
a lot more refactoring, simply because with the current setup the
fetch/ls-refs logic doesn't care that its talking through a
remote-helper where if we went down that route it would need to be aware
of that.
