I would not call it pedantic, and rather support POSIX where possible.

[I am not objective, since I was unexpectedly beaten yesterday. In one of
my programs I used the POSIX options and though everything must be fine.
But I forgot that the old GNU cp had -P meaning --parents; the new cp is
now POSIX compatible, -P means --no-dereference instead, as required.]

Here is a suggestion that requires even less typing and still preserves
"--" for its intended POSIX meaning.

Use "-" to cut the list of certain positional parameters. Like:

  tla undo - file1 file2

The following is ok too:

  tla undo -q - file1 file2
  tla undo -q revision file1 file2
  tla undo -q revision - file1 file2

Adding "--" would be possible too, authough somewhat useless here:

  tla undo -q -- - file1 file2
  tla undo -q -- revision file1 file2
  tla undo -q -- revision - file1 file2
