Perhaps a strategic assertion when adding commands?

Here's a couple of other things we noticed during the discussion that
prompted this patch - lesser improvements than mentioning "apropos"
prominently, I think:

  - The help output doesn't mention which class a command is in; this
    might be useful, for finding related commands.

  - I didn't even know "help all" existed until now.  I couldn't find
    it in the manual, either.
