After spending some time wondering why you wrote the new function I 
realized that it was just enough to nicely fit the needs of the resizing 
functions. The new function also seems to work in all cases I have 
tested so far. Thanks for this, it made it much easier to write the new 
functions for balance-windows. I have replaced `enlarge-window' with 
`adjust-window-trailing-edge' everywhere in the new version:

I am stil waiting for someone to test this and give some feedback. 
(There is still a little bit cleanup to do in the code, but I wait with 
this until I have seen that using the new functions have been tested a 
bit more.) So please test this.

A little recall of the proposed new functions:

  C-x +     -- this now starts a new temporary minor mode for resizing, 
bw-window-resize-mode

In this temporary minor mode the keybindings are:

  +        -- new balance-windows, called bw-balance
  .        --  balance siblings only, called bw-balance-siblings
  arrow keys   -- interactive resize, modelled after GUI keyboard 
resize on w32
