Subject: [PATCH] Keep nxml-prolog-end up to date (Bug#18871)
The change on 2016-01-16 "lisp/nxml: Use syntax-tables for comments"
removed the update of nxml-prolog-end, although it already failed to
work correctly after 2013-10-07 "* lisp/nxml/nxml-mode.el: Use
lexical-binding and syntax-propertize."
* lisp/nxml/nxml-rap.el: New function.
* lisp/nxml/nxml-mode.el (nxml-mode): Add it to
after-change-functions.
