Yeah, it sounds right to me to just bite the bullet and do this
refactoring, limiting the manipulations of the options as much as
possible across contexts. So +1 from me to merge 0001 and 0002
together.
I have adjusted a couple of comments and simplified a bit more the
code in utility.c. I think that this is commitable, but let's wait
more than a couple of days for Alvaro and Peter first. This is a
period of vacations for a lot of people, and there is no point to
apply something that would need more work at the end. Using hexas for
the flags with bitmasks is the right conclusion IMO, but we are not
alone.

OK. Good to know, I have not looked at this part of the patch yet.
