I think the issue with undo is more that there are lots of corner cases that
make a really useful file undo command slightly trickier than it might seem
at first glance, but there is a selective undo patch out there somewhere (and
didn't it even get merged into the latest release?!?).

I agree that in cases where it makes sense, the `--' ought to be optional.
However the way tla typically uses `--', it separates file lists (and some
other sorts of lists) -- but non-file arguments such as revision names still
precede it. This is non-posixy, but it's in fact damned useful, because it
allows one to specify such lists while _still_ omitting preceding non-file
arguments (so they get their default value); since these preceding arguments
are by virtue of restricted syntax not confusable with options, this is a
non-ambiguous, and very handy system.
I would object to any change that made me type more just to be pedantic about
some standard in a way that simply doesn't matter very much.
