And btw, I don't think this patch fixes the general case. E.g., if
receive-pack hits any of its die("BUG") lines, they will not be
prefixed. Most clients wouldn't see them, but ssh ones would.
To fix that you'd have to do a whole async process wrapping
`receive-pack` that just reads its stdout and stderr and muxes it back
over the sideband. But I can think of two roadblocks there:
- I think the original design of receive-pack was _not_ to share all
of stderr with the user, because it might contain secret-ish
server-side things. That's why we have rp_error() which copies to
the sideband.
I don't know how useful that is in practice. We copy the stderr
wholesale from sub-processes like index-pack, so things like file
paths are likely to get leaked there.
- the implementation is a bit tricky, because the die() will take
down the mux thread, too.
