Perl 6 files are not highlighted correctly in UNIX / Win32 format
|Reported by:||azawawi||Owned by:||azawawi|
For STD colorizer, highlighting is messed up if a file is a win32 file (cr-lf causes positions to be mismatched).
For Rakudo/PGE colorizer, highlighting is also messed up if a file is a Unix file under win32.
This relates to how STC manages newlines and positions. We need a general solution to fix both of the highlighters.
