Actually, POSIX requires the behavior you've documented here for the
shell's builtin, as I reported here:
http://lists.gnu.org/archive/html/bug-coreutils/2005-02/msg00085.html.
pwd(1) is by default supposed to print logical paths (by reading $PWD),
and only if that fails or -P was specified, print the physical path.
