Hi Junio,

Since 1.7.7 is out now, maybe you would like to pick this up again.

Cheers,
Clemens

This is the re-rolled version based on current master, without the
backwards incompatible receive-pack --quiet option.

I squashed the tests in and added your unpack(void) fixup.

I have not added Michael's "t5541: avoid TAP test miscounting"
since I cannot reproduce the error:

And there is also this related patch "server_supports(): parse
feature list more carefully", which looked good to me:

 http://mid.gmane.org/[email-masked]

Does it need more work?

--o<--
Currently, git push --quiet produces some non-error output, e.g.:

 $ git push --quiet
 Unpacking objects: 100% (3/3), done.

This fixes a bug reported for the fedora git package:

 https://bugzilla.redhat.com/show_bug.cgi?id=725593

Commit 90a6c7d4 (propagate --quiet to send-pack/receive-pack)
introduced the --quiet option to receive-pack and made send-pack
pass that option. Older versions of receive-pack do not recognize
the option, however, and terminate immediately. The commit was
therefore reverted.

This change instead adds a 'quiet' capability to receive-pack,
which is a backwards compatible.

In addition, this fixes push --quiet via http: A verbosity of 0
means quiet for remote helpers.
