This is great stuff.

The current convention is `am__' as the prefix for internal variables,
and `am--' as the prefix for internal targets.

I'm sure you know this, but the test suite isn't always a very good

Anyway, I think with a few changes (the above, plus the name changes
mentioned in the other email) this should go in on the trunk.
