The following two options control whether minibuffer windows are resized
automatically and how large they can get in the process.
@defopt resize-mini-windows
This option specifies whether minibuffer windows are resized
automatically. The default value is @code{grow-only}, which means that
a minibuffer window by default expands automatically to accommodate the
text it displays and shrinks back to one line as soon as the minibuffer
gets empty. If the value is @code{t}, Emacs will always try to fit the
height of a minibuffer window to the text it displays (with a minimum of
one line). If the value is @code{nil}, a minibuffer window never
changes size automatically. In that case the window resizing commands
(@pxref{Resizing Windows}) can be used to adjust its height.
@end defopt
@defopt max-mini-window-height
This option provides a maximum height for resizing minibuffer windows
automatically. A floating-point number specifies a fraction of the
frame's height; an integer specifies the maximum number of lines. The
default value is 0.25.
