Bug#490253: Adding --quiet option to emacsclient

[Drake Wilson]

Hello, emacs-devel!

In the Debian BTS wishlist ticket #490253, I requested a --quiet
option for emacsclient; currently, it prints a "Waiting for Emacs..."
message that cannot be turned off, which I found annoying.  I have
updated the patch I provided in that report to apply against the CVS
version of Emacs; it would be nice if this feature could make it into
Emacs 23.

CVS-based unified diff is attached.  Comments would be appreciated.

Emacs 23 is in feature freeze.  Could you please send your patch to
emacs-pretest-bug@gnu.org, so that it is entered in our bug tracker?
Then after the release, we'll see if this can be included.  Thanks.

Very well.  Forwarding now.  Hello, emacs-pretest-bug.

(Also re-cc'ing emacs-devel, since I think my actual diff got eaten
somewhere along the way; probably I just miscommanded my mailer.)
