graphics-only was a quick fix for people who want to set pop-up-frames
in their .emacs but get annoyed when they tty-emacsclient end up popping
up frames as well.

More generally we want to specify different display-buffer behaviors for
tty (where frames are fully-overlapping) and graphic terminals (where
several frames may be visible at the same time).
