The Lib/pdb.py debugger fails in the py3k branch.

Traceback (most recent call last):

Why are you using _runscript(), which is an internal routine? I've had a
fair amount of success with other invocations, like pdb.run().

[gpshead]

I was running it by typing "./python Lib/pdb.py Lib/test_foo.py"

Fixed in rev. 58127.
