A window showing a temporary buffer can be fit to the size of that
buffer using the following mode:
@defopt temp-buffer-resize-mode
When this minor mode is enabled, windows showing a temporary buffer are
automatically resized to fit their buffer's contents.
A window is resized if and only if it has been specially created for the
buffer. In particular, windows that have shown another buffer before
are not resized. By default, this mode uses @code{fit-window-to-buffer}
(@pxref{Resizing Windows}) for resizing. You can specify a different
function by customizing the options @code{temp-buffer-max-height} and
@code{temp-buffer-max-width} below.
@end defopt
@defopt temp-buffer-max-height
This option specifies the maximum height (in lines) of a window
displaying a temporary buffer when @code{temp-buffer-resize-mode} is
enabled. It can also be a function to be called to choose the height
for such a buffer. It gets one argument, the buffer, and should return
a positive integer. At the time the function is called, the window to
be resized is selected.
@end defopt
@defopt temp-buffer-max-width
This option specifies the maximum width of a window (in columns)
displaying a temporary buffer when @code{temp-buffer-resize-mode} is
enabled. It can also be a function to be called to choose the width for
such a buffer. It gets one argument, the buffer, and should return a
positive integer. At the time the function is called, the window to be
resized is selected.
@end defopt
The following function uses the current buffer for temporal display:
@defun momentary-string-display string position &optional char message
This function momentarily displays @var{string} in the current buffer at
@var{position}. It has no effect on the undo list or on the buffer's
