bug in my B2-patch

Oops, looks like I goofed the patch I recently posted -- wily will drop the
last character of the command name if it has more than one argument (which
really sucks when the command name is only one character long!). 

In my patch, replace the line

		s_length = blank - l;
 
 with
 
		s_length = blank - l + 1;

Duh....
