Historically, we've kept the docstrings 100% intact between the C and Python versions, even if they are big (see heapq.__doc__) for example.

If there are differences in the "hand written" versions. I would like to have them compared on a case by case basis and resolved.   Unless the C version implements something different, there should be no reason for a docstring difference.  The originals are very close to the specification and to the documentation.  We tried to stay true in part because there are so many niggling details that it would be hard to know without reading the spec.
