Hey bug-gnu-emacs,
In Emacs Lisp mode, the last two backslashes in the string "\\[\\]" are highlighted with (font-lock-constant-face font-lock-string-face). Is this expected?
Clément.

Whether intentional or a bug, it seems to have been introduced
in Emacs 25 builds. I see it there, and I don't see it in
Emacs 24.5 or older releases.

;; Words inside \\[] tend to be for `substitute-command-keys'.
(,(concat "\\\\\\\\\\[\\(" lisp-mode-symbol-regexp "\\)\\]")

Thanks Andreas!
Should this regexp be conditional on being in a docstring? Otherwise please feel free to close as notabug :)
Clément.

Note that this is in no way specific to backslashes inside [].

But then the likes of the following will not be font-locked as you'd
expect:
(message "%s" (substitute-command-keys "Type \\[calc] to return to the Calculator")))
IOW, the doc strings are not the only place where we want this. OTOH,
the probability of having a string where such constructs are used with
no relation to substitute-command-keys is quite low.

Yes, please do that.
Thanks.
