Description:
------------
The usort docs tell us:
"Note: If two members compare as equal, their order in the sorted array is undefined."

Other functions do not do that. The docs of every sorting function should state if the function is sort-stable or not.

Also consider its changelog:


4.1.0	 
A new sort algorithm was introduced. The cmp_function doesn't keep the 
original order for elements comparing as equal.

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.
