Re: "CHANGED outside Customize" in frames customization group

[Richard Stallman <rms@gnu.org>]

    Do I understand you correctly that `frame-notice-user-settings' and
    `modify-all-frames-parameters' should set the `command-args-...' values
    (one for the initial and one for the default frame)?

Yes, that's what I've proposed.  Do you see any flaws in the idea?

      This would require
    a non-trivial reorganization of frame.el.

I think it should be pretty simple.  Only 4 functions in frame.el
seem to refer to default-frame-alist or initial-frame-alist.
So I think that not much change would be needed.

    Note that I was not looking into the command-line arguments and X
    resources issues yet.

Yes, but I think this same approach would work for x-win.el
and would be simple there too.

    I wouldn't know how.  If I simply set `default-frame-alist' in some
    "Custom" way I'll be told that there are unsaved changes.

It looks like `customize-set-variable' does the right job.

So I think this won't be very hard.  Want to give it a try?
