FWIW I just ignored the lexeme parser and did my own on top of the  
basic Parsec primitives.

You may need to do that anyway if you want to support older variants  
of Fortran, which don't actually have keywords and ignore spaces  
outside of string constants (Hollerith constants) --- Parsec's lexeme  
stuff doesn't even pretend to support this.
