#16522 — Passing along cmd.Cmd completion to contained class

I have sub-classes of cmd.Cmd in an arrangement somewhat like

   class Config(cmd.Cmd):
     def do_foo(self, line): print "Fooing %r" % line
     def complete_foo(self, text, line, begidx, endidx):
       ...

   class MyTUI(cmd.Cmd):
     def __init__(self, configger=Config, *args, **kwargs):
       cmd.Cmd.__init__(self, *args, **kwargs)
       self.config = configger()
     def complete_config(self, text, line, begidx, endidx):
        magic_here(self.config, text, line, begidx, endidx)

I've been sparring with getting MyTUI.complete_config() to reach 
into self.config for completions so I can type things like

   (cmd) config <tab>
   (cmd) config foo <tab>

and have it suggest from Config as if I had done something like

   def do_config(self, line)
     self.config.cmdloop()

and then asked for completions.  That would mean that the first 
one would act like Config.completenames() and the second one 
would act like Config.complete_foo(...)

Is there a best way to get this pass-along behavior?

Thanks,

This is not tested, but maybe it'll work :)

def complete(self, text, state):
    if text.startswith('config):
        return self.config.complete(text, state)
    return Cmd.complete(self, text, state)
