[v3] restore C++STYLE formatting

[Jonathan Wakely]

the C++STYLE guide got mangled on conversion to docbook, this restores
the indentation so it's actually useful again. I also fixed a few
errors and added some markup.  I might convert the whole
<literallayout> block to proper <para>s some time, but not today.

	* doc/xml/manual/appendix_contributing.xml: Indent code examples
	to match original C++STYLE document. Fix typos and syntax errors.
	Add some basic docbook markup.
	* doc/html/*: Regenerate.

tested with 'make doc-html' on Fedora and checked in to trunk.
