src/Tools/jEdit/src/jedit/protocol_dockable.scala

replaced Document.Node_Text_Edit by Document.Text_Edit, with treatment of deleted nodes;
Document_Model.pending_edits: more robust treatment of init, including buffer reload event (jEdit 4.3.2 produces malformed remove/insert that lacks the last character);
tuned;
