I've done a litte audit on the usage of '--' :

*tla commit -- files
*tla undo -- files

'--' is use as command line switch, so it's not transparent and don't
follow POSIX behavor.

I would really prefer to see a '--files' option along with
'--files-list' (notice the 's').

But sure, '--' is short and handy.

(And a '--file-list' without argument or '--file-list -' that read
standard input could be handy too: i will try to propose a patch for
that ).

*tla changes -- limit

Here it could really be a 'traditionnal' command line option with a
single argument.

* tla archives

"--" stop the whole parsing process.

    115         case opt_double_dash:
    116           {
    117             goto no_more_args;
    118           }
    119         }
    120     }
    121 
    122  no_more_args:


* tla changeset

a "--" in the command line lead to specific error:

     97         case opt_double_dash:
     98         usage_error:
     99           opt_usage (2, argv[0], program_name, usage, 1);
    100           exit (1);

* tla inventory -- [directory]

doesn't work but it's described in help

* Other command don't have special handling of '--'.

This make tla behave differently than other GNU tools .
