Subject: (echo_area_display): Don't perform a display update from
X-Git-Tag: emacs-pretest-21.0.90~413
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=d4358b37bec6762190437fc14a5a4fbc1b894465;p=emacs.git

(echo_area_display): Don't perform a display update from
inside redisplay.  The update will happen anyway at the end of
redisplay, and it can confuse redisplay (GC messages while
redisplaying, for instance.)
