| | | | | | functions in child shells now even have $n passed to them! :) (in main shell it still doesn't work)

| | | | | | | | | | Add TODOs. Disable redir4.right part where we differ from bash. It is not a bug per standards. Add a few tests, one is in hush-bugs section: and_or_and_backgrounding.right. It will likely bite users in real world usage.
