In many places a carriage return is not valid whitespace and should thus not be colored as such. In some of these places a vertical tab or form feed is maybe valid whitespace, but it would be ugly or even wrong to color them because they are not part of the subsequent comment or keyword. This fixes https://savannah.gnu.org/bugs/?60456.
