(I'm doing this python.el checkin with some byte-compiler warnings.  These
warnings existed before Nick Roberts or I applied any of the pdbtrack
changes, and look very clearly like preexisting, incomplete adoption of
code from python-mode.el.  I'm going to next look at settling those
warnings, though I don't have time for a major reconciliation of the two
python-mode implementations.)
