Re: [PATCH/RFC 0/6] fetch with refspec

We've got a lot of refs, but pretty frequently we only want to fetch
one.  It's silly for the server to send a bunch of refs that the client
is just going to ignore.  Here are some patches that fix that.

Let me know if this seems reasonable.

Thanks for working on this!

I had a similar goal back then for non-http traffic and that series
exploded in size[1]
The issue at my attempt was non http traffic would require a protocol
update such that
the client speaks first to transport the refspec to the server. To
make "client speaks first"
happen, we'd need to have a protocol v2. So that attempt of mine
stalled as it seemed like
a huge thing.

This series looks small and reasonable from a cursory read.

Thanks,
Stefan

(and I'll start in on another round of index-helper as soon as this is sent!)
