have docstrings beginning with one-line summaries.
A new docstring was added to formatter. The docstring for os.py
was updated to mention nt, os2, ce in addition to posix, dos, mac.
optional third argument gives a maximum number of delimiters to parse.
The new function splitx() is like split() but returns a list
containing the words as well as the delimiters.
