As I've moved over to emacsclient from gnuclient, I've found a couple of areas where it's behavior is awkward, although not wrong per se.  

This patch adds:
* a --quiet option to suppress informational messages from emacsclient
* In emacsclientw, defaults to --quiet and --no-wait
* adds --wait and --verbose options to override the defaults in emacsclientw

If it's deemed to be too late in pretest for these that's fine, but this is a small change and leads to better interaction.

Actually it works very nicely.  emacsclient expands the local filename into an absolute filename (as it currenty does) and prefixes that with the Tramp prefix when it sends it to Emacs.  I use emacsclient no differently than if the emacs instance were local, and it communicates the correct filename (not only in the correct directory, but on the correct remote machine).

And yes this could be done with a script around emacsclient, but the script would have to make the filename absolute itself (because the Tramp prefix will make the filename look absolute already).  Obviously, not difficult, but with a small patch, emacsclient can do all of it out-of-the-box.
