I read the earlier thread and I still don't quite understand this
point.  What makes it difficult?  X seems just like any other option
that takes a string parameter (which is easily supported by getopt at
least; I haven't played with parse_options but I certainly hope it's
as good as getopt).

The string parameter (say, $x) is translated directly into "--$x" and
passed as exactly one argument of the argv array to the subprogram.
Easy, right?  Plus Junio already wrote a patch to do it (which I'm in
the process of forward-porting) and it seems pretty straightforward.

Perhaps I'm missing something.

Thanks,

Avery
