Bad markup in doc/web2/howto.object-traversal

New submission from khorn <[email protected]>:

Two problems with the markup in this file:

 1. A number of `<pre>` blocks are marked up as `<pre class="literal-block">`.  This class is not mentioned anywhere in the lore docs that I can find.  I think it should be `<pre class="python">` (all of the mis-marked blocks contain python code).
 1. The `<pre>` block starting on line 333 has `<` and `>` signs, where it should probably use `&lt;` and `&gt;`.
