2009-04-10hush: fix a few thinkos in function support; make it work on NOMMU;Denis Vlasenko
functions in child shells now even have $n passed to them! :) (in main shell it still doesn't work)
2009-04-10hush: first stab at function support. argv passing is not coded yet.Denis Vlasenko
Only very rudimentary testing was done.

2009-04-10hush: tighten up "for" variable name check.Denis Vlasenko
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.
