Summary:
My change had a couple of problems:
* utf8 character width logic was completely wrong for characters that need 3 or 4 bytes
* `Array.listArray (start, end)` produces an array where `end` is a valid index
* because of ^ the `arraySize` logic also has to change

Summary:
This converts the code to monadic style, so that
we can in the future:
* stop threading the `Document` parameter everywhere
* keep some state, like regexp match cache (I've already checked that it makes a substantial difference)
There should be no difference in performance or behavior
at this point.

Summary:
This works around https://github.com/haskell/cabal/issues/4350
If we don't do this files get compiled multiple times
and cabal is unhappy.
