There is now a second version of this patch on that bug, which will
also accept Seq objects as arguments to the split, strip, lstrip and
rstrip methods, plus has the start of some tests too.

We (Peter, Martin, Bruce and Leighton) seem to have reached an
agreement about adding split, strip, lstrip and rstrip methods to the
Seq object with the behaviour (arguments and defaults) to follow those
of the python string as closely as possible.

I'd like to encourage others lurking on the list to comment too, but
unless anyone objects, I intend to add these methods in CVS this week,
together with an updated unit test and updates to the tutorial.
