bug#16738: Errors while resizing vertically

[martin rudalics <rudalics@gmx.at>]

> Another one without a clear recipe. I am using the following function on a fairly regular basis:
> 
> (defun es-maximize-window-vertically (&optional window)
>     (interactive)
>     (cl-callf window-normalize-window window)
>     (unless (eq window (frame-root-window))
>       (window-resize window (window-max-delta window))))
> 
> In combination with:
> 
> (setq window-min-height 1)
> 
> Sometimes it causes errors such as the ones below. In this state a) I can't resize any windows, using the above function. b) I can still resize using the mouse. c) Once I do, I usually can resize once with this function, but then I get a similar error again.

Hopefully fixed with revision 116504 on trunk.  Please try again.
