I have decided I can unfortunately not fix this bug now. A quite 
complicated rewrite of `enlarge-window' is needed.

I run into this when I tried to finish the rewrite of `balance-windows'. 
I have written a new version of balance-windows and it works (I 
belieive) but since Kim's patch gave some new possibilities I wanted to 
enhance it a bit. The rewrite contains three functions:

1) A rewrite of balance-windows (at the moment called bw-balance, C-x + +)
2) A new function to balance only the siblings in the tree from 
`window-tree' (bw-balance-siblings, C-x + .)
3) A temporary mode for resizing current window with the arrow keys 
(started with C-x +)

The bug in enlarge-window is more visible now because of 3 above. 
However if you try to resize using the mouse you see the same problem.

Please test the new functions. They are in
