Subject: (do_switch_frame): Remove unused parameter NO_EVENT, add
X-Git-Tag: emacs-pretest-21.0.101~315
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=1e8324d9a0eaec8e4de2a9a3b309ab77e1ae827b;p=emacs.git

(do_switch_frame): Remove unused parameter NO_EVENT, add
FOR_DELETION.  Avoid resizing the mini-window of the selected
frame if FOR_DELETION is set.
(Fselect_frame, Fhandle_switch_frame, Fdelete_frame)
(Fmake_frame_invisible): Change calls to do_switch_frame for new
signature.
