Not your itch. But if you have time you may want to fix fetch-pack
too. It has the same problem. fetch-pack.c:get_pack() with
use_sideband == 0 passes fd to start_command(), then later its
caller transport.c:fetch_refs_via_pack() closes the handle again.

In this code block, there is "close(out);", we may need to set fd = -1 too.

I was puzzled by this packet_flush(out) for a while because I thought
"out" was already closed. Turns out when stateless_rpc is true, a new
pipe is created in pack_objects() and "out" is not closed. So
everything is still good (and messy).
Life would have been simpler if fd was _always_ closed by
send_pack(), like in c20181e (start_command(), if .in/.out > 0, closes
file descriptors, not the callers - 2008-02-21).
