Catches both DOS and old-style Mac line endings. Alternatively, you can
use s.splitlines():
s = "\n".join(s.splitlines()) + "\n"
This also makes sure the string ends with a \n, which may or may not be
a good thing, depending on your application.
Do people consider this a bug that should be fixed in Python 2.4.1 and Python 2.3.6 (if it ever exists), or is the resposibility for doing this transformation on the application that embeds Python?
It could theoretically break something: a program that uses unix line-endings but embeds \r or \r\n in string data.
But this is rather theoretical, I don't think I'd have a problem with fixing this. The real problem is: who will fix it, because the fix isn't going to be as trivial as the Python code posted here, I'm afraid...
