8.1 [path.generic] says: "The filename dot-dot is treated as a reference to the parent directory." So it must be specified what "/.." and "/../.." refer to.

Add a statement what the parent directory of the root directory is.

[2014-02-07, Beman Dawes suggests wording]

[ 2014-02-11 Issaquah: Implementation defined. See wiki notes for rationale. Beman to provide wording for review next meeting. ]

[ 2014-05-22 Beman provides wording, taken directly from POSIX. See pubs.opengroup.org/onlinepubs/9699919799/xrat/V4_xbd_chap04.html#tag_21_04_12 ]

Proposed resolution:

1. Change 8.1 [path.generic]:

   > The filename dot is treated as a reference to the current directory. The filename dot-dot is treated as a reference to the parent directory. What the filename dot-dot refers to relative to root-directory is implementation-defined. Specific filenames may have special meanings for a particular operating system.
