optparse functionality missing

Hi,

optparse doesn't seem to have a pass-through capability for command line 
parameters/options that were not registered with add_option.

I'm not the first person to complain about this.  On Wed Mar 17 08:20:10 CET 
2004, there's a thread titled "Perceived optparse shortcomings" where someone 
complains of the same problem.

In a scripting environment, I often want to strip some of the command line 
options off the argument list, and then pass the remaining options to another 
module that is deeper in the tool chain.

optparse doesn't seem to allow this, as far as I can tell.  It requires that 
you register all possible options with add_option() or an error is flagged. 
When my second tier module is an autoconf script that could have hundreds of 
its own options, it seems dumb to have to register all those options, just to 
have to reconvert them to command-line options so that I can pass them to the 
autoconf command line.

Could we get a mode added to optparse so that any commandline 
parameters/options that are not registered via add_option() can be in the args 
return value of the parse_args() method?

-Jeff
