  To: notmuch

Make the default behaviour for --client the same as emacsclient
default: do not create a new frame. Add a new option --create-frame,
passing the same option to emacsclient to create a frame.

---

With this, 'notmuch-emacs-mua --client' does what I want, which was
not possible with any combination of options before. Please see if you
can still do what you want!
