[Bug-gnubg] Minor output bug in commandline

[Massimiliano Maini]

(No game) help set evaluat
set evaluation - Control position evaluation
parameters

Usage: set evaluation <subcommand>
Available subcommands
:chequerplay        
   Set evaluation parameters for chequer play
cubedecision    Set evaluation
parameters for cube decisions
movefilter      Set parameters
for choosing moves to evaluate

The colon (:) after "available
subcommands" is ugly.

Responsible code is in gnubg.c (CommandHelp(),
line 1837):

    if( pc->pc &&
pc->pc->sz ) {
        outputl(
pc == &cTop ? _("Available commands") :
         
       _("Available subcommands")
);
        outputc(':');
