I've just dug deeper into this morass...

Posix http://www.opengroup.org/onlinepubs/007904975/utilities/pwd.html
requires that pwd (whether a shell builtin, or the command) default
to 'pwd -L' and hence assume that $PWD is correct and that you can
use ".." to travervse backwards over a symlink.

This is contrary to historical practise for everything except ksh!

The shell ought also support 'cd -L' and 'cd -P', the current 'cd'
builtin is actually a hybrid of the two.
Again the default is the ksh semantics.

The shell could be made conformant by adding a 'set -o physical' option
(as is done in pdksh).
