What is git rev-parse HEAD needed for?

How about something like this?

if [ -e $abs_top_srcdir/ChangeLog ]; then
    DATEPARAM=`awk '/^[0-9]+-[0-9]+-[0-9]+/ { print "--date=" $1; exit }' \
        $abs_top_srcdir/ChangeLog`
else if [ -d $abs_top_srcdir/.git ]; then
    DATEPARAM=`git show -s --format=%ci | awk '{print "--date=" $1}'`
fi

(If $DATEPARAM is not set, pod2man would fall back to its current
behavior.)
