conversion of newlines in a string

[Skaperen]

because we don't know a priori if it is a Windows file or a Mac file.

so, \r has a different meaning depending on which. i recall that, now. i was thinking in a narrow box trying to cover potential cases. i will know a priori whether it is Windows or Mac so i could use a different function for each. i was wondering if i should implement my own set of functions or use what Python might have.
