Buffer local variables:
phw--window: nil (=> unrestricted) or a window-object (=> bound if live)
phw--size:
  nil : dynamic
  0   : goal - shrink to fit
  N   : goal - N lines
  t   : goal - maximize

(=> not local, dyn), t (=> max)
phw--size-phw:  nil (=> not local, dyn), t (=> min)


 PHW |   Edit    |
 low | nil |  t  |
-----+-----+-----+
 nil |	4  |  3  |

1: minimize PHW
2: fit PHW
3: fit edit

Unbind BUF from WIN
- remove BUF from WIN's ring
- clean WIN's ring
- kill BUF's phw--window

Bind BUF to WIN
- if BUF's phw--window is non-nil then unbind from there
- set BUF's phw--window = WIN
- clean WIN's ring
- make BUF most recent entry in WIN's ring

Operations:
- display BUF in WIN
  => bind previous BUF to WIN (BUF remains unbound)
- move BUF
  => unbind BUF from current WIN
- exchange BUF1 and BUF2
- kill BUF
  => unbind BUF from current WIN
