Hmph, am I reading the patch to send-pack.c correctly?
It detects if the other side supports the capability and leaves it
in atomic_push_supported variable for later use, and also requests
the feature to be activated when atomic_push is set, but I see no
logic to link these two together, e.g. error out when atomic_push
is true and atomic_push_supported is false (or turn it off with a
warning, or whatever).
