Don't indent unrelated widgets following widget of type 'other

* lisp/wid-edit.el (widget 'other): Use \n instead of the %n escape in the
:format property of this widget.  If %n is used at the end of the
format string, unrelated widgets get indented.  (Bug#12533)

* test/wid-edit-tests.el (widget-test-indentation-after-%n)
(widget-test-indentation-after-newline)
(widget-test-newline-and-indent-same-widget): New tests.
