198 Explanation: For the list variable `ibuffer-saved-filters',
199 elements of the form (STRING (FILTER-SPECS...)) are deprecated
200 and should instead have the form (STRING FILTER-SPECS...), where
201 each filter spec is a cons cell with a symbol in the car. See
202 `ibuffer-saved-filters' for details. The repaired value fixes
203 this format without changing the meaning of the saved filters.
205 Alternative ways to save the repaired value:
207 1. Do M-x customize-variable and entering `ibuffer-saved-filters'
210 2. Set the updated value manually by copying the
211 following emacs-lisp form to your emacs init file.
