OK, it turned out to be a little easier to do this than I originally
thought, so the changes are checked in now.  I plan to work on block
comments next.

This should work, but "clear sin" does not seem to be working
properly.  Using "clear functions" works, but clearing a function
by name should also work.  This looks like a bug in clear.
