Description
I've tried to hack a solution but I appear to be lost in a sea of unfamiliar regex syntax.
It appears that line 520 is close to the issue:
;; Constant values (keywords), including as metadata e.g. ^:static
("\\<^?:\\(\\sw\\|#\\)+\\>" 0 font-lock-builtin-face)
somehow the end of word matcher \\> inhibits # from being the end of a keyword.
