BTW, in the absence of this alist in Emacs, you can code it up yourself
with a quick advice like (guaranteed 100% untested):

   (defun handle-scripts-in-start-process (args)
     (if (string-match REGEXP (nth 2 args))
         `(,(nth 0 args) (nth 1 args) "bash" "-c" ,@(nthcdr 2 args))
       args))
   (avice-add 'start-process :filter-args #'handle-scripts-in-start-process)
