I don't have a strong preference but if I need to pick one I would
choose option (c) or option (d). The option (a) is out of the question.
I'm attaching a patch that implements option (c). While reading the code
I noticed that I left a comment that should be removed by commit
b9639138262. 0002 removes it.
