this relate to file-truename which doesn't seem to have the flaw(!?)
as described above!?
file-truename actually follows the path on the device. See
realpath(1) and realpath(3) man pages. Unlike the system utilities,
however, file-truename only follows the actual path until it ends on
the device, then appends any components remaining in the given name.
expand-file-name, file-name-as-directory, and similar functions
manipulate strings, and so won't necessarily correspond to any real
directory entries (they might contain symlinks, as well as the
occasional anomolous "/..").
