67c1c7b456 use get_local_var_value() rather than getenv() when working with 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 2009-04-24 06:26:18 +00:00

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.
