EmacsLisp: Char literal `? ` (as a space) is swallowed.

[jasonm23]

In the following example:

(make-string 10 ? ) ;; a string of 10 spaces.

is modified to:

(make-string 10 ?) ;; a string of 10 spaces.

Since Common Lisp has no special meaning for ? I am not sure what the right solution is or what the goal of parinfer-rust is for EmacsLisp support.
