Subject: gsu subcommand: Use gsu_getopts.
X-Git-Url: http://git.tuebingen.mpg.de/?p=gsu.git;a=commitdiff_plain;h=c2d03a6157867608fe2daef1c8bbfc3d727c0d72

gsu subcommand: Use gsu_getopts.

This makes the prefs command error out on invalid options
and avoids the expansion of the possibly unset parameter $1.
