Re: Removing no-back-reference restriction from syntax-propertize-rules

Hmm... in tex-mode.el we do:

    ("\\\\verb\\**\\([^a-z@*]\\)"
      (1 (prog1 "\""
           (tex-font-lock-verb
            (match-beginning 0) (char-after (match-beginning 1))))))))

and indeed, `tex-font-lock-verb` then restricts it to only match on
a single-line, so a regexp with a backref would be simpler (I think
I evolved that code from that of perl-mode.el where regexp operations
can take similarly delimited args, but those can span several lines so
a regexp was not appropriate).

\lstinline (from `listings` package) is probably another example, yes.
