Patch updated on 2005-12-02 15:55 EST (GMT -500).
Updated patch includes changelog for reference.xml. 

As recommended by Daniel Convissor, "Seems like an explanation of the pre-5.1 and post-5.1 return values would be most helpful in the returnvalues refsect." This is not included in the patch. If there is a sample of what this type of change might look like, please point me to it and I will add it to the patch file.

This bug has been fixed in the documentation's XML sources. Since the
online and downloadable versions of the documentation need some time
to get updated, we would like to ask you to be a bit patient.

Thank you for the report, and for helping us make our documentation better.

"When called with an empty string the result will always be TRUE in PHP < 5.1 and FALSE since 5.1." in ref.ctype
