Fixed #14502 again -- saner verbatim closing token

Previously, the closing token for the verbatim tag was specified as the
first argument of the opening token. As pointed out by Jannis, this is
a rather major departure from the core tag standard.

The new method reflects how you can give a specific closing name to
{% block %} tags.
