Uh, as far as I know and am concerned, that is _not_ the correct
behaviour for most programs.
for instance, the syntax for 'cat' is:
cat [-benstuv] [-] [file ...]
and that's as it has historically been (modulo additional options,
If you specify a file name, that is the end of option parsing, period.
I don't think the new behaviour you describe should be the default for
_any_ existing program in our source tree, unless you can provide some
documentation (e.g. a standard like POSIX.2 or one of the X/Open ones)
that mandates it.
