Flexable Collating (feedback please)

[Ron Adam]

Fixed...


Changed the collate() function to return None the same as sort() since it is an 
in place collate.

A comment in _test() doctests was reversed.  CAPS_FIRST option puts words 
beginning with capitals before, not after, words beginning with lower case of 
the same letter.


It seems I always find a few obvious glitches right after I post something.  ;-)

Cheers,
    Ron
