Minibuffer height problem

[Lennart Borgman]

The minibuffer does not resize correctly and eventually there are some 
scrambling of the content in the minibuffer (the last line could be 
shown a bit up) when the following function is run. I have tested this 
on w32 with CVS from today.

(defun test-minibuffer-resizing()

Testing minibuffer window height
================================

This is a several line long prompt. Test this with a window with
a smaller heigh. The height should be big enough to hold the
whole promp. The minibuffer will not be big enough to show the
whole prompt string.

Is there maybe a limit on the minibuffer window size? If there is
one it is not described in Info (aka Emacs Manual).

This is just another paragraph to show the problem ;-)
