Every frame has at least one font: the one it uses to display the
text.

The question is: would some Lisp code call font-family-list expecting
it to always return something non-nil.  Since in Emacs 23 GUI frames
and TTY frames can be found in the same session, I'm not sure what is
the right answer to that.
