already do that.  my fallback "get most things down to a reasonable
level" refile and refile goto were ok until recently.  then they
became untenably slow.  i can't refine it more without missing stuff
that i need.

so only useful if i set the variable with duplicate stuff?


delete-dups seems suspicious but what do i know.  i wonder if
cl-delete-duplicates is more efficient.

(defun delete-dups (list)
  "Destructively remove `equal' duplicates from LIST.
Store the result in LIST and return it.  LIST must be a proper list.
Of several `equal' occurrences of an element in LIST, the first
one is kept."
  (let ((tail list))
    (while tail
      (setcdr tail (delete (car tail) (cdr tail)))
      (setq tail (cdr tail))))
