+;; Ben originally coded this in 2005/01 to return a list of lists each
+;; containing a single string.  This is apparently derived from use of
+;; this list in completion, but in fact `read-color-completion-table'
+;; already does this wrapping.  So I'm changing this to return a list of
+;; strings as the TTY code does, and as expected by r-c-c-t.
