* Speed-up intersection whenever PyDict_Next can be used.

conversion).  Hopefully I've not messed up the formatting.

- rearrange so two small sections become one; this avoids an extra
  page in the HTML format

- add link to the datetime module

  file.xreadlines()

- slightly simplify a couple of examples
- clean up some markup

* Add comment on the future of the sets module.
* Change a variable from "input" to "data" to avoid shadowing a builtin.
* Added possible applications for str.rsplit() and itertools.tee().
* Repaired the example for sorted().
* Cleaned-up the example for operator.itemgetter().

- note the interpreter's -S option

patch removes dependencies on the old unsupported KoreanCodecs package

semantics to include subtypes.  Most concrete object APIs then had

not including subtypes.

The PyDict_CheckExact() macro wasn't created at that time, so I've added
it for API completeness/symmetry - even though nobody has complained
about its absence in the time since 2.2 was released.

Not a backport candidate.
