Comment 4 for bug 388673

I'm looking at implementing this again. I decided I don't like the idea of a separator. It's just geeky and 99% of the time unneeded. Rather, it would be better to have the option take two arguments. But getopt can't handle that right now. However... optparse can. And it's a little more fully-featured. I'm looking into porting commandline.py to optparse.
