Thanks! Included in 'pu', but I have separated out the whitespace changes
into a separate commit to make the diff of your commit easier to read.

While I recommend making sure that no *new* trailing whitespace is added
by a patch, taking out *existing* trailing whitespace should be done in a
separate commit if it is to be done at all. And whitespace should never
be removed from the header, because it will only be added back
again by a trigger when the patch is graduated to the development
branch in Clearcase.
