c0ea329297 hush: fix a few thinkos in function support; make it work on NOMMU;
functions in child shells now even have $n passed to them! :)

b7d8c0dbbd hush: first stab at function support. argv passing is not coded yet.
Only very rudimentary testing was done.
 With function support off, code growth is zero, with it on:

1fd1ea4395 hush: tighten up "for" variable name check.
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.
