This all sounds really nice.

How will parse_cmdline behave when 'extra' arguments are specified ?

Can it distinguish between commands like bind in which the last arg
should be 'gobbled up' and commands such as msgwait which should only
accept a specific number of args ?

The current behaviour, which is consistent, is to ignore extra args. eg.
see my unsetenv vs your unsetenv patch.

I've always found the current behaviour somewhat irksome :)

Thanks for all the work.
