Subject: gui: Treat dialog exit code 255 just like 1.
X-Git-Url: http://git.tuebingen.mpg.de/?p=gsu.git;a=commitdiff_plain;h=64712f59781b7d1029773b6f555f74c964129040

gui: Treat dialog exit code 255 just like 1.

Dialog exits with code 255 if escape was pressed. This change makes the
escape key more useful in the main menu invoked via _browse() since it
no longer terminates the program but results to show the parent menu.
