When an emacsclient running in a terminal is connected to an Emacs
instance running in a graphical environment, running `emacsclient -c'
from a comint buffer (such as M-x shell) creates a frame in the
graphical environment, where it may be inaccessible to the user who
ran the command.

To reproduce:
1. Run `emacs --daemon' on a system with a graphical display.
2. Login to the system using a terminal with no graphical display. You
    could do this by switching to another virtual terminal (Ctrl-Alt-F1
    works on Ubuntu), or SSH in from another machine.
3. Run `emacsclient -c' or `emacsclient -t' in the terminal to connect
    to the running Emacs instance.
4. Inside Emacs, run M-x shell.
5. In the M-x shell buffer, run `emacsclient -c'.

Ideal behavior: emacsclient creates a frame on the current terminal.
Actual behavior: emacsclient creates a graphical frame in the
   environment in which it was launched, which is inaccessible from the
   terminal.

Possible questions:

Q : Why would you want to run emacsclient from within M-x shell? Why
     not just do whatever you want to do in the frame you already have
     open?
A : Normally the user isn't launching emacsclient directly. Instead,
     a script might be launching emacsclient as part of a larger
     workflow.

Q : Why not just launch emacsclient without the '-c' option?
A : Without the -c flag, emacsclient works well to edit a file or
     series of files, but it doesn't support more complicated tasks.
     For example, a script might want to launch an ediff session, and
     wait until the ediff session exits. The easiest way to do this is
     to use `emacsclient -c' and wait for the connection to be closed.
