Subject: gui: Introduce _set_dialog_ret().
X-Git-Url: http://git.tuebingen.mpg.de/?a=commitdiff_plain;h=021cb6acbe9be83506f27e9eff3cd434e6daf149;hp=021cb6acbe9be83506f27e9eff3cd434e6daf149;p=gsu.git

gui: Introduce _set_dialog_ret().

The improved exit code handling for dialog(1) also makes sense for
the other invocations of dialog. This patch abtracts out the logic
into the new internal _set_dialog_ret() function.
