mkunit.sh was a little dumb, it didn't handle a number of things correctly.
I've written a new program that basically does the same thing, only it's much more clever, and does many more of the translations and conversions better, including the #line directives. Also, I dropped nids, we don't need it anymore. But now I'm ready to write some serious tests for myriad.
