Re: Problem in temp-buffer-resize-mode

[Richard Stallman]

    Thanks for reporting this bug.  In fact a test like

       (=  (frame-width) (window-width))

    is used quite frequently in Elisp code and may fail in all these cases
    just as it did for you.  FWIW these tests should be replaced by calling
    a function `window-full-width-p' (the function `display-buffer' uses to
    check whether it should split the largest window).

Would you like to make these fixes, then ack?  They should be fixed in
Emacs 22, and will then get transferred to the trunk.
