As promised, here is the test input I use for testing the C program macros.
I've tried to put instances of most tricky cases here, so that people
tweaking the macros can make sure they don't break anything.  There are
also enough examples that you can get an idea of what C programs look like
in general.  You can see from the three #defines that non-initial tabs
don't work very well.
