[1.3.X] Fixes #16072 -- incorrect documentation for multiple expressions inside a blocktrans tag

    This will have {{ myvar }} inside.

    {% endblocktrans %}

If you need to bind more than one expression inside a ``blocktrans`` tag,

separate the pieces with ``and``::

You can use multiple expressions inside a single ``blocktrans`` tag::

    {% blocktrans with book_t=book|title and author_t=author|title %}

    This is {{ book_t }} by {{ author_t }}

    {% endblocktrans %}

.. note:: The previous more verbose format is still supported:

   ``{% blocktrans with book|title as book_t and author|title as author_t %}``

This tag also provides for pluralization. To use it:

    * Designate and bind a counter value with the name ``count``. This value will

apply.

.. note:: The previous more verbose format is still supported:

   ``{% blocktrans with book|title as book_t and author|title as author_t %}``

Reverse URL lookups cannot be carried out within the ``blocktrans`` and should

be retrieved (and stored) beforehand::
