Hmmm. Yeah, this does need fixing, but I don't want to lose the
"examples". Some have stuff like this before the description:

* .. code-block:: c
*
* TH_LOG(format, ...)

which retains it, but many don't. Can you add the code-block:: c
sections where they're missing so this doesn't lose the syntax hints
when just looking at the header file alone.
