I though you expected that the names are not generated inside the module
since you changed the manual according to my commit (r68072) and backported
both commits.

I like the current state. Perhaps not so convenient when advanced users
work in the command line but in all other cases it requires you to be
explicit, thus better for beginners (who don't have to guess the new name)
and the GUI (wxGUI can automatically show the new maps only when they are
specified in the command line).
