Mark,

Here's another squashed commit of your changes for the undef shipping 
change:

http://github.com/jonjensen/interchange/commits/ship-return-undef

It is easiest to work with these patches on GitHub if you use a separate 
branch for each change, and then later if we squash the commits so we 
don't get every intermediate tweak on the way to a final patch.

Please let me know if that looks ok.

Thanks,
Jon
