Let's step back a bit. We recommend that you NEVER parse ls output, as
it is inherently ambiguous and difficult to parse. MUCH better is to use
stat instead of ls, at which point you can get directly at the
information you want without having to post-process potentially
ambiguous output.  If anything, added documents should point people to
stat, not to bad ways of parsing ls.
