Actually I tried exactly as you suggested 1 month ago [1], but I'm not
sure if that is the best way forward now after comments from Douglas,
and so I was proposing to just extend the same option.

Anyway I'll wait for comments  for 1 week and then eventually provide
patchs for both options as they are quite trivial in any case.

Thanks,
Nuno
