Re: messages override minibuffer input

[Richard Stallman]

    Yet quite generally, it confuses me when I type something and
    suddenly the text I have typed disappears. Even when the message
    disappears again when I continue typing, a smooth work flow requires
    that I know the last character I typed before the message appeared
    so that I know where to continue typing while something else is
    displayed.

If we put such messages at the end, that may cause the minibuffer
to grow by a line.  Would you find that disturbing?

If not, perhaps the thing to do is to put the message below the
current input, always growing the minibuffer.  Or put the message
above the minibuffer contents.  What would you think of that?
