Subject: play: Convert com_prev() to lopsub.
X-Git-Tag: v0.6.0~2^2~48
X-Git-Url: http://git.tuebingen.mpg.de/?p=paraslash.git;a=commitdiff_plain;h=f4c330d6693eb3da840d9f2f8210997095987956

play: Convert com_prev() to lopsub.

The arg count check can be removed from the command handler, and the
pointless help text of the commit has been removed because it said
more or less the same as the summary text.
