Hope code below did not mess anything. "entity-map" subdir is explicitly
excluded, some of the defitinions seem to need trailing whitespace.

parse_data: no entity map for `urlnam'
parse_data: no entity map for `[shy   ]'

unset BKP

find . \
     -type f \
     -not -iwholename '*.git*' \
     -not -iwholename '*.pc*' \

     -print0 | xargs -0 sed -i${BKP} -E "s/[[:space:]]+$//"
