Consider using completing-read-function by default
Created by: Wilfred
This package currently requires grizzl, and users who want other completion engines must configure it. How would you feel about changing the default:
(defcustom fasd-completing-read-function nil
"The completion function to use for `fasd' completion.
If not set, use `completing-read-function'."
:type 'symbol)
This would mean that the package just works for users of ido, helm and counsel without any additional configuration.
