Re: [PATCH 2/2] upload-pack: use stdio in send_ref callbacks

IIUC, the most notable difference between this round and the
previous one is that now we are no longer buffering more than one
packet worth of data because we let the stdio to accumulate them.
I was a bit surprised that we still want to have a strbuf inside
this structure (which is there only because it wants to persist
during the whole conversation with the other side).

Ahh, sorry, scratch that.  I do remember the discussion/patch that
it was hurting to make calls to strbuf-init/strbuf-release once per
ref, and it is an easy way to have the structure here to reuse it.

But that means this majorly overlaps what Patrick is already doing
in his ps/ls-refs-strbuf-optim topic.  Perhaps these should be
rebased on top of that topic branch, I wonder?
