I don't understand.  Under Nick's proposal, calling splitext with no
keyword parameters results in the exact behavior we have today, so
it's obviously backward compatible.  If you use a keyword parameter,
you're using a new feature implemented in 2.6, so there is no
expectation of backward compatibility unless and until the keyword
parameters are backported.
