Thanks. I rewrote it to support variable-length indentation using an indent
stack approach, as I apparently have quite a bit of data in formats such as
this:

 1
  2
     3
    3
   3
  2

That seems to be just as stable and catches the indentation at level 0
thing as well.

The grammar is more or less the same, replacing indentedBlock() instances
with OPEN + OneOrMore + CLOSE instances, but parsing times are orders of
magnitude better. 

Thanks,
Philipp
