IMO, it should be the other way around, i.e. no error but a '+' to
signify an ACL, for two reasons:

1. Transperency. Since the UNIX permissions are emulated, one could
argue that all files should have the '+' displayed...

2. Probability. If the file is busy there's good chance that the file
has an ACL.

I view the '+' as a reminder that "there's more to it than what is
shown" and I think that would be right thing to convey for busy files.

I think this behaviour would be the least surprising...
