More POSIX shell standards stuff

[Bart Schaefer <schaefer@xxxxxxxxxxxxxxxx>]

The first one involves the -P option of "cd", and the second one has to do 
with the changes PWS made a couple months ago to the "test" builtin.  In 
the latter case, it looks like they're going to decide to bless zsh's 
original behavior, so we might want to consider backing out the change or 
making a setopt for it.
