I don't know the answer to that question, Dirk, but my understanding
is that "\r" is unnecessary on any of Linux/Unix, Windows, or the
recent releases of OS X. I write and share lots of multi-OS scripts
for NoteCase Pro and stopped including the carriage return token years
ago without any subsequent complaint from any users (regarding the
missing "\r").

As I understand the situation, only the early versions of OS X that
ran on a RISC processor wanted the "\r" and Apple did away with that
when they rebuilt OS X on Unix.

Best regards,

Paul
