This is getting more and more a philosophical discussion, since these values
are ignored by a 6502 CPU anyway:-) I'm resetting anything that I don't want
to be set. I think this is good practice, even if it may be superflous in the
given case. Why do you think that the AND is evil in this place?

They are only used on CPUs not supported by cc65, so we don't need to care
about that, I think.
