;; advice to prevent ido from using flex matches on huge lists of files
;; with enough characters typed and blocking for an absurd amount of time
;; after a stupid typo
;; The value af-ido-flex-fuzzy-limit is the maximum value of the product
;; of the number of characters the user has entered and the number of
;; options in the ido list.
;; The default value was determined experimentally and seemed to be
;; the boundary of sane wait times when this was written.
