Subject: Use lexical-binding in bug-reference.el
X-Git-Tag: emacs-27.0.90~3261^2~19

Use lexical-binding in bug-reference.el

* .dir-locals.el: Set bug-reference-url-format in all modes, not just
changelog mode. Use (eval . (bug-reference-mode)) as described
in (info "(emacs) Specifying File Variables")
* lisp/progmodes/bug-reference.el: Use lexical binding.
(bug-reference-unfontify):
(bug-reference-fontify): Mention args in docstring.
