There's conventional wisdom that .pyc files are
compatible within a single minor revision of Python,
but I can't find any documentation that says this
explicitly.

This assumption is important to Debian's Python
packaging policy, so if it's true, could it be
documented somewhere (probably the marshal or
compileall module documentation)?

Thanks.

It is documented here: http://www.python.org/peps/pep-0006.html

Is that sufficient?

It's also effectively documented here:
http://svn.python.org/projects/python/trunk/Python/import.c

That is a list of all magic numbers which denote the python
revision.

Yes, PEP 6 is great, thank you! Sorry that I forgot to check
there.
