Re: Emphasize the character to be typed next in *Completions*

[Richard Stallman]

    +(defcustom completion-emphasis-region 'first-different-character
    +  "Region emphasized in the completions in *Completions*."
    +  :type '(choice (const first-different-character)
    +            (const common-prefix)))

I don't want to include this option.  It isn't useful.  Would you
please make a simplified version which does not have this?

To support every alternative that anybody has suggested
is NOT a design goal for Emacs.
