Re: Suggestions for mode-line-format changes

[Richard Stallman]

    Any ideas/pointers to how one can easily right-align text in a
    (mini-buffer) window?

You could calculate its width, subtract that from the total frame width,
and indent that much.

As Miles reminded us, this would be a kind of echo area
display--nothing to do with the minibuffer.  When the minibuffer is
active, this text will not appear.

The minibuffer is displayed as an ordinary buffer, displayed in a
buffer, so there is no special code for displaying it.  There is
special code for displaying the echo area.
