ef3e7fdd3b hush: push down expansion var in handle_dollar() 
Declare the variable in the scope it is used rather than the entire
function scope so it's obvious it is only used there.

ff64fb9e31 hush_test: filter test output to avoid C lib differences 
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.

93cadc2fdd hush: implement type 
Implement support for the POSIX `type` command.  Only POSIX stuff is
supported here, no bash extensions like -p or -P.

In the process, split the $PATH searching code out of builtin_source() and
into its own find_in_path() function so we don't duplicate it.

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.
