Combining --add-modules ALL-MODULE-PATH with --module-source-path

Sorry for reviving such an old and pretty dead thread but I still
wonder about this. The gist is: Wouldn't it be nice to somehow (e.g.
with `--add-modules ALL-MODULE-PATH`) convince multi-module
compilation to compile all modules, regardless of whether they are
reachable from the initial module?

 so long ... Nicolai
