Hi Emacs developers.
In misc.texi: 687..689,
>>> start here
The variables @code{resize-mini-windows} and @code{max-mini-window-height} (@pxref{Minibuffer Edit}) control * when the output is considered too long for the echo area.
<<< end here
Currently, there is nothing(empty) at * markd positiin, but I think * should be 'window resizing' or something like that.
I am not English native, so I am not sure this is correct.
