pactree(8) and Optional Depends.

Hi, It would be nice if pactree(8) had an option to include optional dependencies, i.e. treat them as dependencies. I was trying to obtain them as part of `pactree -s -r', but non-reverse would be useful too. I'm not sure if they should be marked as optional in the output somehow, e.g. a trailing ` ?', reminiscent of an extended regular expression's operator. Please keep me CC'd. -- Cheers, Ralph.
