Fix syntax highlighting of # character

The # character is used regularly in URIs, but because it is also used
as the comment character, syntax highlighting incorrectly colours some
URI literals with the comment colour.

Since the syntax highlighter is applied before the regular expression
highlighter, the latter needs to be told to override the former.
