Because I originally voted that this felt like a bug I wanted to state
that after determining that this has already been legacy system
historical practice for a very long time that I wouldn't change it
now.  Portability of applications is more important.

This isn't a feature that could be working in a script for someone.
It isn't something that was recently removed that would cause a script
to break.  A script will run now with the same behavior across
multiple different types of systems.  I think we should leave things
unchanged.
