Unfortunately, I also messed up the manual entry.  Anyway, I'm changing
this currently to make the window fit the size of the buffer as it is
displayed and also counting the real size of the mode and the headerline
and a couple of other things.  If you want to fix this yourself, call
(window-min-size) instead of (window-min-size nil nil t).

Thanks for the report, martin
