* As found by Karsten, the reference count was not initialized in

_ReplaceAtPositions(), and _DoCharacterEscape() (we don't need to preserve
  it, though, as it must be 1).
* Factored out an _Alloc() method which is now always called when the private
  data is allocated. It also takes care of correct initialization (and thus
  fixes the above problem).
* This fix finally allows turning on reference counting again, thanks Karsten!
* Minor cleanup, renamed "oldAdr"/"newAdr" to "oldString", resp. "newString".
