FWIW, I support Phillip on this. There can be no question that the old behaviour was expected.

IMO this is just gratuitous breakage. The only fix that shold be made is to the splitext documentation to match the docstring.

A change to the documented behaviour should require a __future__ import for at least one version. That's even assuming that the change is desireable (I don't believe so). We have multiple anecdotes of actual, existing code that *will* break with this change. So far I haven't seen any actual code posted that is currently broken by the existing behaviour.
