[Lars Ingebrigtsen]

branch: master
commit b16b4d730e0535484393aa8c01744fc609e61d92
Author: Peter Oliver <git@mavit.org.uk>
Commit: Lars Ingebrigtsen <larsi@gnus.org>

    If the daemon’s TTY is our only frame, create a new frame
    
    * server.el (server-process-filter): If there won't be a current frame
    to use, fall back to trying to create a new one (bug#11033).
