Re: Suggestions for corrections to executable.el - use of PATHEXT

[Davis Herring]

Tiny augmentation:

(defvar executable-binary-suffixes
  (if (memq system-type '(ms-dos windows-nt))
      (let ((pathext (getenv-internal "PATHEXT")))
        (if pathext
             (nconc (split-string pathext ";") '(""))
          '(".com" ".exe" ".bat" ".cmd" ".pif" "")))
    '("")))

(Indentation made into spaces; don't compare to nil with `eq'; add ".pif" 
and "".  I add back "" because with Cygwin, you have commands with no 
extension; if my assumption is wrong and `system-type' isn't set 
Windowsishly then, drop that entry.)
