[Python-Dev] Re: Unix line endings required for PyRun* breaking embedded Python

 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.

s = s.replace(\r, \n[\n in s:])

Fredrik s = s.replace(\r, \n[\n in s:])

This fails on admittedly weird strings that mix line endings:

 s = abc\rdef\r\n
 s = s.replace(\r, \n[\n in s:])
 s
'abcdef\n'

where universal newline mode or Just's re.sub() gadget would work.
