A collection of string operations (most are no longer used).
Warning: most of the code you see here isn't normally used nowadays.
Beginning with Python 1.6, many of these functions are implemented as
methods on the standard string object. They used to be implemented by a
built-in module called strop, but strop is now obsolete itself.
