I don't think that in general you want to fold multiple empty lines into
one. This would be my prefered regex:

    s = re.sub(r"\r\n?", "\n", s)

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.
