Subject: [PATCH] Return on user cancellation of delete operation

* src/delete.c (delete_status_handler): Return on ERROR status, if the
error location is set to "delete_key.secret" and the code is either
CANCELED or FULLY_CANCELED, which indicates a situation that the user
selected "No" on the confirmation dialog.
