I have a patch for that now.  It actually shrinks the Indic machine
considerably (from ~16kb to ~5kb).  So I definitely like it.  However, the
failure numbers go way up.

We need to seriously do something about tracking expected output so we can
stop relying on Uniscribe output and improve the expected results as we go.

I'm working towards that, slowly...
