Summary: optparse should support arbitrary number of arguments

Initial Comment:
Currently, the number of arguments an option 
can/should have, needs be defined.

This is done using "nagrs".

parser.add_option("", "--my-option", nargs=3)

The problem is that at times it isn't predictable how 
many arguments you'll be receiving.

I request the implementation of this feature in 
optparse, where the following could be possible.

parser.add_option("", "--my-option", nargs=*)

Thanks,
Ritesh

I share effbot's view on that, but leaving to Greg to
decide. In any case, this is a feature request.

I don't know of any program that uses command line switches
with a variable number of args, partly because you then
cannot distinguish between option arguments and normal
arguments.

I you still need this, you can implement a custom callback,
I think.
