Some people like to use ${?} rather than $?, so make sure we support all
the special single char vars that use this form.

The getopt function in some C libraries wraps the option in single quotes
while others do not. Avoid the issue by running sed on the output and
strip all quotes.

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.
|
|
fix some more obscure bugs.
a new redir4.tests is known to fail.
