Re: CUA mode cursor color

[Richard Stallman]

      1. Using `M-x cua-mode' doesn't print a message in the mode-line,
         whereas using the menu option does.  Why not always print a message
         (many other mode toggles do, and they probably all should), and make
         the menu option and `M-x cua-mode' exactly the same?

There is a possible problem with making these toggles display a
message inthe echo area: Lisp programs may want to call them, and
often it is inappropriate to print messages in those cases.

Long ago, every minor mode was supposed to be controlled by a
variable.  Lisp programs could set or bind the variable, so there was
no reason to call a toggle function.  But this is not true in general
any more.

At present, we have turn-on-X-mode functions for some minor modes, and
variables you can set or bind for other minor modes.  And there may be
some cases which have neither one.  It is a confusing situation.
I wonder if we can straighten it out.
