Ebola in vector key syntax

(lookup-key [(control x) 4 a]) => 2 ;; WTF? I use this function constantly, it _has_ to be there. (lookup-key [(control x) ?4 a]) => add-change-log-entry-other-window ;; O.K. I'm not going crazy. Check for Ebola: (lookup-key [(control x) 4]) => list-directory (where-is-internal 'list-directory) => ([(control x) (control d)]) I think it's wrong in this context that single digit numerics in vectors get treated as control characters. A character is a character is a character and not an integer.
