I'm not a big fan of overloading arguments, i.e. if the daemon isn't
automatically started for all uses of --client, I'd rather there was
another argument like --auto-daemon so that there are at least 4 ways of
invoking

| n-e-m                                       | start a new emacs instance, and kill it after |
| n-e-m --client                              | like emacsclient                              |
| n-e-m --client --create-frame               | like emacsclient -c, destroy after send       |
| n-e-m --client --create-frame --auto-daemon | like emacsclient -c -a, destroy after send    |

Since there are probably only 3 users, this should be sufficient ;).
