This is the prefix to be prepended to each line typed without
the command prefix.  The default is ' ', which is like 'say '.  To
emulate ircII's command_mode, set this to ''.  Be sure to use the
single quotes.

&addhelp("set cmdprefix", <<"EOH");
This is the prefix that determines whether an input line is a
