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.
