Re: doc for fit-window-to-buffer should emphasize "height", not "size"

[Richard Stallman]

    "Size" should be replaced by "height", since this command does not
    change the window width.

Thanks.

    By the way - is there no command to change the window width to fit the
    buffer (e.g. fit its longest line)? Why not?

Because horizontal splitting isn't used often enough to make it worth
having one.
