misc: remove some trailing whitespace newly introduced

The commit (merge) referenced below added some useless
trailing whitespace, and this patch will correct such.

[ this also updates the NEWS file for the buglet fix ]

Gosh, if folks cannot coax their editors into avoiding
such crap they should remove the '.sample' suffix from
their '.git/hooks/pre-commit.sample' file. Thereafter,
git itself will reject changes with whitespace errors.
