Yes, that is an annoying misfeature.  The other related thing to watch
out for is this:

>>> print " a b ".split()
['a', 'b']
>>> print ":a:b:".split(":")
['', 'a', 'b', '']
>>> 

... in other words, if you make the separator be anything other than a
space, you need to take special care to strip off any null elements that
might have been accidentally generated at the start and end.
