No, POSIX also knows about it (and actually I've been told that it is
older than ``):

Any idea where this would be documented, or of an example shell where
this becomes a problem?

http://www.opengroup.org/onlinepubs/009695399/utilities/pwd.html says
that pwd should write to stdout "an absolute pathname of the current
working directory, which does not contain the filenames dot or
dot-dot", and does not say otherwise in
http://www.opengroup.org/onlinepubs/009695399/utilities/xcu_chap01.html#tag_01_13
