Re: list-colors-display: display all color names

[Richard Stallman]

      When there are more than two color names, the first
    of them is displayed in the background example, and all others are
    separated by comma in the foreground color example.  For instance,

I like this change, but it needs to set truncate-lines to t
in that buffer in case there are so many names that they 
don't all fit.

Also, on each line please sort all the various names.
