internal use.  Make sure the maxlevels and level parameters get
	passed to recursive invocations.

	- handles recursive data structures
	- formatting based on a PrettyPrinter object
	- allows a maximum nesting depth to be specified
	- provides safe repr()-like function which does not pretty-print

Removed pprint.py from the README; it's now in the standard lib.

Test it extensively by using pick.

(with some slight formatting changes).

Feature requests:

- Make it a class (everything should be a class);

- support recursive data structures (like pp.py on the ftp contrib site).

Added pformat() function:  formats object to a string representation with
	no trailing newline; returns the string.

contained in commands created by those same widgets.

buffering, so to get the normal behavior back, I set it to
unbuffered.

This used to be done whenever stdin was interactive.  Now we only do
it when the -i flag is given.  Also (and this is the real reason for
this fix) we explicitly allocate a buffer -- this seems to be
necessary on Windows.

string_append().  These must be artifacts of GvR's rewrite.

Fixed some typos in the leading comment (and re-filled the
paragraphs).

Hope you don't mind, Guido.

The function parse_qs currently calls urllib.unquote on the
value of the field submitted, but not on the name.  It needs
to do both.

This completes the getpath.c checkin.  Note that to enable this in an
existing build tree, you'll have to edit your Setup and Setup.in file
to remove the $(DESTLIB) from all the PATH variable definitions.

Idea and first three implementation rounds due to Barry -- after that
I spent another day on it, hopefully it's enough for now :-)

(Wait for the checkin to Setup.in.)
