Bug report

Bug description:

cmd.Cmd does not allow the definition of readline completion delimiters, therefore,complete_*() methods will fail with completion options containing dashes (or other characters in readline's default list of delimiters).

Defining aCmd.completer_delims (by defaultNone) and then callingreadline.set_completer_delims(self.completer_delims) (ifCmd.completer_delims is notNone) after importing readline will do the trick.
