[st...@apache.org]

Author: stsp
Date: Fri Nov 25 11:43:53 2016
New Revision: 1771298

URL: http://svn.apache.org/viewvc?rev=1771298&view=rev
Log:
Introduce a special 'delete' editor callback for updates of incoming moves.

* subversion/libsvn_wc/wc_db_update_move.c
  (tc_incoming_editor_delete): New. Deletes a working node instead of removing
   a row at a particular op-depth as in the local-move update case.
  (update_incoming_moved_node): Invoke the new function.
