* bug#25708: 25.1.91; Allow users to inhibit printing for 'emacsclient -c -t'

Sometimes I want to eval some elisp at the command line exclusively to
set up some buffers for me to work with in a new frame. For example, to
diff two files, I often do:
emacsclient -c -e '(ediff "fileA" "fileB")
This works, but emacsclient annoyingly prints the result of the eval'ed
expression to stdout. In this case, I'll get:
#<buffer *Ediff Control Panel*>
This output is annoying, and it can't be redirected (`emacsclient -c' on a
terminal fail to launch if stdout is redirected, for obvious reasons).
It would be great if emacsclient had a way to inhibit printing the
result, for cases where the user is only eval'ing the expressions for
their side effects.

Emacsclient claims to have that functionality already. From the
usage-message:
-q, --quiet Don't display messages on success
This should, in my opinion, cover the case of successfully eval-ing
forms. However, -q currently has no effect on output from emacs, it
only inhibits messages about connecting to emacs.
The attached patch should prevent emacsclient from printing non-error
output from emacs to the terminal.
With this the terminal stays quiet after exiting the client frame when I
do "emacsclient -q -c -e '(+ 2 3)'". Without the -q, the terminal
prints 5 as before.

Thanks, but I think this warrants a separate command-line option, or
maybe a special argument to --quiet. Otherwise, it would be an
incompatible change in behavior.

Looks good (but see minor comments below). Let's wait for a few days
to give others a chance to comment.

Each comment should end with a period and 2 spaces. Like this:

Do we really need the "non-error" part here? Errors don't manifest
themselves via return values, I think.
Thanks.

I'm not intimately familiar with the protocol between emacs and
emacsclient, but emacsclient handles a number of different return
messages from emacs. Two of which (-print and -print-nonl) I made -u
apply to.
Another possible return message seems to be -error, which also results
in stuff being printed by emacsclient (in this case to stderr). -u does
not suppress that kind of printing. I thought it worth specifying, but
if that path is in practice never used, I can take that wording out.
What do people think?

Then it's not a good word to describe the option. Better would be
--suppress-output.

I thought it succinctly expressed what the flag did, but I have no
objection to --suppress-output.
Attached is the latest version of the patch, with all objections raised
so far addressed.
