Well, we have 'bzr help topics'. And we also would like a way to do "bzr
help PLUGIN". Like "bzr help bzrtools".

And many plugins have the same name as their command. So we would
probably also want "bzr help plugin X" or maybe just 'bzr help-plugin X'.

So whatever mechanism we use for topics could also be used for topics.

I would prefer "bzr help topic foo" or "bzr help-topic foo", to using a
namespace scheme. But 'bzr help plugin:foo" could work.
