Sorry to jump in late, but here are my thoughts.

The '--' switch has the meaning (or at least the feeling) I'm done with 
arguments, everything after this is a filename.
And that is exactly how tla handles it. The difference, though, is that 
it requires that switch to supply *any* filenames.

So I have to wonder. Why can't "tla undo", et. al. just take a list of 
filenames. So that if I type:
        tla undo
It does a standard undo, but if I use
        tla undo file1 file2
It says, hey, there are specifically listed files, lets only undo them.

Is it an issue with the command line parser?

*I feel* like we could switch to a more POSIX-y format just by allowing 
files any time, and then have '--' only mean no options can occur after 
a '--'.
