Rather than waiting around for an answer, I went ahead and made my
modifications to python-mode.el.  While I've tweaked emacs lisp stuff in
the past, I've never been confidant about it, given the complexity of many
elisp packages.  So now the question is whether they're good enough to put
back into the official version, and if so, how would I do that?

For what it's worth, I'm including the code below.  It's relatively small,
a definition for py-tab-always-indent and a few lines changed in
py-indent-line.

used."
