Subject: gui: Make some functions return void.
X-Git-Tag: v0.4.10~1^2~3
X-Git-Url: http://git.tuebingen.mpg.de/?p=paraslash.git;a=commitdiff_plain;h=b55f405f8005821ffa369b929bc0b419da62683d

gui: Make some functions return void.

All callers of these functions ignore the return value, so get rid
of it.
