The quotes of an empty string ('' or "") should be colored just like
those of a non-empty string, because otherwise the text *between* two
empty strings on the same line gets colored.
Add an extra rule to discolor triple quotes again to not make them
look like valid by themselves.
Also, remove six superfluous backslashes.
This addresses https://savannah.gnu.org/patch/?9801.
