Yes. In the old stemmer -s is removed from -ous early on so -ou- is removed
later to compensate, but in the new stemmer -s is not removed after -u-
(cactus, ferrous, locus etc) so -ous survives as an ending until step 4.
There has been some php work on the stemmers by "dark panda": You can find
the relevant correspondence if you put "php" in the front page search box -
but maybe you have found it already.
