Hmm... would it? Or should two split points with nothing between them produce empty strings, i.e. you would have to do x.split(('\r\n', '\r', '\n')) to get the behaviour of x.splitlines()?

Right, Georg's example would be unintuitive given the current behavior of str.split which will happily provide zero-width matches when it hits separators in sequence.

Perl bypasses the issue by having split (http://perldoc.perl.org/functions/split.html) take a regex; I've only rarely used this for complex matches, though. I tried a Google code search for

lang:perl split\(?\s?\/\[        (simple multiple separators)
lang:python \.splitlines\s?\(
lang:python \.split\s?\(

but the number of results seems to oscillate between 300 and 100000, so that didn't help much.
