What seems to be going on is that haskell-indentation simply isn't
prepared to deal with hierarchical module names at all, or qualified
imports.

operator (.), which it considers to be valid syntax. Operators are not
valid in module statements, however.

I'm going to try teaching it. Hopefully I won't break anything in the process.
