Parser or lexer mess-up

[simonpj]

This program gives a parse error:

module Par where

f x = x
  where
-- ######### x86_64 machine code:
    g y = y
    h y = y

With the HEAD we get:

Par.hs:7:8: parse error on input `='

This is killing the stage2 build of the HEAD, in ByteCodeFFI:

ghci/ByteCodeFFI.lhs:444:26: parse error on input `='

The problem is something to do with the comment (!). Remove it, and all is fine. I think something to do with Haddock. But surely comments should not mess up code? Programmers unaware of Haddock will not even look at the comments when trying to correct parse errors!

Happily 6.8 seems ok.

Moving the comment to the indentation level of the 'g' makes the error go away. So I think this bug is correctly stated as " '-- #' comments affect indentation context.". This is up my alley so I'm going to have a go at fixing it.

Squashed.

Many thanks for the patch, dfranke! I've just applied it. Sorry for the delay.
