Because it's possible to have the permission string you stated above on
a file which is not locked. The point is, if the file is locked, we can't
say anything about the permissions and trying to indicate "the file is
locked" by fiddling with the current set of available values isn't going
to be successful. If you're looking for a way to be able to tell from
'ls -l' whether a file's permissions are represented truthfully or not
(because the file is locked), then Eric's proposal, or something like it,
is what you're looking for.
