executable-set-magic update

lisp/progmodes/executable.el does not appear to support magic numbers of the 
form `#/usr/bin/env interpreter’.  One way to extend support is via the 
attached diff which merely adds a new variable 
`executable-interpreter-path-absolute’.  Set the new variable to nil and 
variable `executable-prefix’ to “#!/usr/bin/env “.

It would also be nice if `executable-set-magic’ were supported beyond 
`sh-set-shell’ (in lisp/progmodes/sh-script.el), so I implemented a minor mode 
that adds the following hook to find-file:

(defun script-set-magic ()
  "Look up interpreter associated with current major mode in
`script-set-magic-alist' and call `executable-set-magic'."
  (let ((interpreter (alist-get major-mode script-set-magic-alist)))
    (if interpreter (executable-set-magic interpreter)))

The minor mode file is available as:
