Wrong line number reported with CPP and line beginning with #
If I compile
{-# LANGUAGE CPP #-}
module Bug where
{-
# hi there!
-}
*
I'm told of a parse error for the * on line 10. But that * is line 9!
The problem is that, with CPP on, the line number counter gets confused if a line begins with a #, perhaps after whitespace.
I actually hit this and was confused in real code.
