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.

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.
