Summary: Wrong line count in parsec under linux on dos-style files

Initial Comment:
Parsec doubles the line count (reported e.g. in a parse error) when run (at least on a linux box) on DOS-style files (with DOS-style newlines)

I have GHC 6.0

  Modified files:
    libraries/parsec/Text/ParserCombinators/Parsec Pos.hs 
  Log:
  Fixed line count bug. That is: unix and dos files are correctly
  handled by unix, and dos. Old mac files are still not correctly
  handled on unix and dos but we feel that this is less of a 
problem
  now with macosx.

As a temporary fix, you may comment out the following line in the 
ParsecPos.hs file.  This fix will make correct line numbers being 
displayed on Unix OS's as well as Microsoft's  irrespective of where 
the text input files are created (this fix will probably result 
in a bug on Mac's), 
 
Comment out the line 
       '\r' -> SourcePos name (line+1) 1 
in updatePosChar function in ParsecPos.hs 
 
Keep a local copy of parsec, and pick up parsec from here, instead of 
from GHC's text package.
