"--quiet" for git-push does not suppress remote hook output

[Laszlo Ersek <lersek@xxxxxxxxxx>]

Hi,

being a total novice in git internals, it seems like
"builtin/receive-pack.c" (on the server) forwards any receive hook
output with copy_to_sideband() back to git-push (on the client), even if
git-push was invoked with "--quiet".

And "case 2" in demultiplex_sideband() seems to print that "band" to
stderr (on the client), despite "--quiet".

Is this intentional? I'd prefer "git push --quiet" to suppress remote
hook output (unless the remote hook fails).

Thanks!
Laszlo
