Yeah, the -c option to emacsclient means "create a new graphical frame".
Currently, you need to omit -c if you want Emacs to reuse an existing
frame.

The trouble with this is that if no existing graphical frame exists,
that will create a tty frame.  Unfortunately, we don't offer an easy way
to change this behavior yet.  This ought to be fixed, though probably
for Emacs 24.2.
