Benno Schulenberg 544351f3be syntaxes: replace [[:space:]] with [[:blank:]] to exclude carriage return
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.
