Just on --add-modules ALL-MODULE-PATH with --limit-modules. This combination 
isn't implemented at run-time, I think we just missed it at the time. In 
practical terms it's not interesting of course but just mentioning it here 
because I don't think jlink with --add-modules ALL-MODULE-PATH and 
--limit-modules is interesting either.

The main thing to deal with here is --add-modules ALL-MODULE-PATH without 
--module-path so I'll focus on that part.
