[merge]:code_block directive to rst

[tonib]

Hi,

I am mainly writing in rst wiki syntax. But one of the things missing in this is to syntax highlight code block.

In the trac wiki syntax this is possible with the {{{ #!cpp }}} syntax.

I looked around on the net and found a solution in the leo project. They have introduced a code_block directive. So one writes

.. code_block:: Python

To get a code_block with python syntax.

I have attached how they implement it in leo. It isn't very complex. I dont know how to integrate it in trac.

Leo is distributed under a python license which is a BSD style license. So it should be no problems to use it in trac.

I added the directive.

The only changes that were needed to do was in trac/wikimacros/rst.py

I've attached the patch.

If you include it the wiki should be updated. I can do it but I would need to know if the patch will be included into the tree.

Bigger patch including this is in #655
