Note that I've since brought this up on python-dev, and consensus there so
far is that Python's dict.setdefault() should change to require both
arguments too.  Alas, I did find one use of 1-argument dict.setdefault() in
real code, in the docutils package.  It was a bad use, though, using a
1-argument dict.setdefault() call followed by a "del" statement to achieve
what dict.pop() does directly.

Thank _you_!  I'm still not entirely sure why, but adding a new feature on a
branch works really well under SVN -- the mechanics of this have been dead
easy.
