Hmm.  The documentation is at variance with the code, which clearly says

 *     Returns string, with first letter of each word in uppercase, all
 *     other letters in lowercase. A word is defined as a sequence of
 *     alphanumeric characters, delimited by non-alphanumeric
 *     characters.

and indeed implements it that way.

It looks like we changed the code to match what Oracle does on
7/27/2003, but forgot to fix the documentation.  Will fix, thanks
for the report.
