[issue1234674] filecmp.cmp's "shallow" option

[Steven Barker]

Steven Barker added the comment:

A recent Stack Overflow question (http://stackoverflow.com/q/23192359/1405065) relates to this bug. The questioner was surprised that filecmp.cmp is much slower than usual for certain large files, despite the "shallow" parameter being True.

It is pretty clear to me that the behavior of filecmp.cmp does not match its docstring with respect to "shallow". Either the docstring should be updated to match the existing behavior, or (more likely?) the behavior should change to match the docs.
