help: pass subtopic into help()

Now that we have multiple directories where help topics can live,
we need a mechanism to access them. We already use "." to
separate topic from section. So it seems logical to also use "." to
denote the sub-directory of a topic.

This patch teaches the help command to parse out the possible
sub-topic and pass it to the help system.

To run the tests, do:

cd tests/
python run-tests.py
