 What is cd -P supposed to do? The bash and zsh docs don't really make
 sense and as far as I can tell from running them experimentally -P
 must stand for "work properly". The ksh docs are a little clearer, but
 anyway this behavior is the default in sh.
 Should we have sh's cd builtin accept and ignore -P?
