[Кириченко Георгий]

sorry, i am do't use splited view before, this is new patch:
Its work as
1) document has one remaining view
  => ask to save and close
2) document has more views in the current area (example: split 
window)
  => no need to ask, still have at least one more view visible
3) document has more views in another area in same workingset
  => ask to save and close in all areas
4) document has more views in another area in another workingset
  => no need to ask, still have at least one more view visible
