+For the "customlist" argument, the function should return the completion

+The function arguments are:
 	ArgLead		the leading portion of the argument currently being
 			completed on
 	CmdLine		the entire command line
 	CursorPos	the cursor position in it

 By default, user-defined commands do not accept a line number range.  However,
