Subject: 26; Add macro `with-hook-added'
Date: Mon, 3 Dec 2018 10:47:12 -0800 (PST)

Enhancement request: Please consider adding a macro such as this, to
facilitate temporary use of a hook function.

(defmacro with-hook-added (hook function &rest body)
  "Evaluate forms in BODY with FUNCTION added to HOOK, then remove FUNCTION."
  (declare (indent 1) (debug t))
  `(unwind-protect (progn (add-hook ',hook ',function) ,@body)
     (remove-hook ',hook ',function)))
