2009-04-24do not tell people they can enter "help" if help has actually been disabledMike Frysinger
2009-04-24use get_local_var_value() rather than getenv() when working with ↵Mike Frysinger
PS1/PS2/HOME, respect the PS2 env var, and make sure that the prompt changes whenever PS1/PS2 changes so we dont have to re-exec the shell to get a changed prompt

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

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.
