Add block name to endblock (feature request)

[yary h <spm-django@…>]

For some large pages, I find it useful to add comments showing the names of the blocks that an "endblock" is for:

{% block outer %}
  .. many lines here ...
  {% block inner %}
    .. etcetera ..
    {% block questions %}
    .. a whole lot of stuff here ..
    {% endblock %} {# questions #}
    ... etc ...
  {% endblock %} {# inner #}
  ... blah ...
{% endblock %} {# outer #}

The {# endblock comments #} help me keep my sanity. What I'd like to do is write:

    {% endblock questions %}
    ... etc ...
  {% endblock inner %}
  ... blah ...
{% endblock outer %}

and have django make sure that the endblocks match with the named block. Helps with the "internal documentation" and helps me see the structure and catch cut/paste errors. The endblock naming would be purely optional, of course!

This is a good idea, as long as it's optional. Anybody care to write a patch?

Here's a good start.

Actually, that's probably more than a start. It works for me :)

The try/except was overkill

(In [4489]) Fixed #3351 -- Added optional naming of the block in "endblock" tags to ensure
correct nesting. Thanks for the patch, SmileyChris.
