[New-bugs-announce] [issue6066] POP_MARK was not in pickle protocol 0

New submission from Collin Winter <collinw at gmail.com>:

Lib/pickletools.py incorrectly thinks POP_MARK was part of protocol 0;
POP_MARK was only added with the introduction of protocol 1 in r7753.
This mistake led me down a dead end while fixing another pickling issue.

Alexandre, can you double-check me on this? Feel free to bounce this
back if you don't have time.

I'll port this to py3k. I'm leaning toward a backport to 2.6; any
thoughts on that?
