Subject: 30.0.92; emacs-lisp font-locking word regexp
Date: Mon, 11 Nov 2024 00:30:46 -0600

Starting from emacs -Q, put the following into a buffer with
emacs-lisp-mode

  (setq foo "\\<foo\\>")

The part "foo\\" of the string "\\<foo\\>" will get
font-lock-variable-name-face, which looks odd.

I believe, this is due to a clause in lisp-mode.el that says

         ;; Words inside \\[], \\<>, \\{} or \\`' tend to be for
         ;; `substitute-command-keys'.

But this assumption is not always correct, in particular if ">" is
preceded by "\\", which happens when constructing regexps.
