I guess the two settings would be combined like this, then:

navigate = False, descend = False : show a single level
navigate = False, descend = True  : show all levels at a single level
navigate = True, descend = False : show a single level, nothing to navigate
navigate = True, descend = True  : show a level at a time

(A better name than "navigate" might be beneficial.)

I also took the liberty of trying to document the * and ** behaviour on the 
Wiki, and just to clarify, is the only difference between those wildcards 
that ** shows subrepositories whereas * doesn't? This confused me because ** 
is often used by tools to mean "recurse", but the descend setting seems to 
control actual filesystem recursion, not the path specification.
