bug#3677: 23.0.95; facemenu-read-color should not require match

[I apologize if this is a duplicate.  M-x report-emacs-bug doesn't
appear to have called my sendmail-send-it function, so my original
report is likely to be rejected as spam from many recipients.]

  M-x set-cursor-color RET #9ef RET

  -> [no match]

The same thing happens with set-foreground-color and
set-background-color, all of which call facemenu-read-color, but not
with set-face-foreground and set-face-background, which do not.  All
above mentioned functions do completing reads on color names, which is
appropriate, but they should also accept #xxx, #xxxxxx, rgb:xx/xx/xx,
etc.  If you do M-: (set-cursor-color "#9ef"), it works, so this is
clearly a case of the wrong kind of completing read being done.

In facemenu-read-color, in the let statement, require-match is
initialized this way:

	 (require-match (not (eq window-system 'ns)))

I believe it should always have the value nil so that people are free
to enter colors in alternative ways.
