Seems like a pretty simple fix, did the trick.

Docs could also use something specifying that this will not work with standard getopt syntax, -mN does not work, only -m N. Similarly --max=N will not work.

Using the node getopt library seems like it would be useful here, no?

Thanks for this. I implemented the opts parsing part of node.io before there were any libraries available to do it for you. I plan on bundling a dep in v2 which will use the standard getopt syntax.
