but 'ls --' is equivalent to 'ls'.

'tla undo' is not equivalent to 'tla undo --', in fact the latter does
not work at all, the '--' command switch require argument : '--' change
the behavior of the command instead of changing only the command line

But, the point is not to prove if tla behavor is POSIX compatible
(it's not ;), but to think if it's acceptable. And it's probably an
endless discussion.

(That's why i made this bug report a wishlist).
