giving it a slight facelift

with spaces in filename.

I changed the module to use string methods instead of the string
module.  Also, instead of stripping the last character of the filename
(assuming this is the linefeed), I strip trailing whitespace (assuming
creating files with trailing whitespace in their name cannot possibly
be a wise idea).

(Note that I believe that /F's "workaround for broken uuencoders" is
no longer needed since the recent fix to binascii.c, but I'll leave it
in since it appears pretty harmless.)

Use != instead of <> since <> is documented as "obsolescent".
Use "is" and "is not" when comparing with None or type objects.

The attached patches update the standard library so that all modules
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.

with trailing garbage generated by some broke uuencoders.
