I should have mentioned that this bug exists also in older versions of
Emacs, at least back through Emacs 20.7.

    Subject: wrong frame is current when after-make-frame-functions


    The Subject line might not describe this well. Do this:

    1. emacs -q. The default (frame-char-width) is 8.

    2. Reduce the frame character size (default font) to a small number,
       so that, for example, the (frame-char-width) is, say, 5. You can do
       this, for instance, with (modify-frame-parameters frame (list (cons
       'font new-font-name))), where new-font-name has a smaller size.

    3. (setq after-make-frame-functions
             (lambda (fr) (message "width: %s" (frame-char-width))))

    4. C-x 5 f foobar

    5. The message that appears shows that, at the time
       after-make-frame-functions was executed, the (frame-char-width) of
       the selected frame is 5, not 8.

    However, debugging shows that the new frame is selected when
    after-make-frame-functions is executed. The problem is that
    frame-char-width does not take this selected frame into account, for
    some reason - it uses the previous frame to calculate the character
    width.

    In GNU Emacs 22.0.50.2 (i386-mingw-nt5.1.2600)
     of 2005-04-16 on LAPTOP
    Distributor `Microsoft Corp.', version 5.1.2600
    configured using `configure --with-gcc (3.4)'
