Fewer places to change when you add a new option; in particular, not
copyfuncs or equalfuncs. Also, the way you are doing it is gratuitously
unlike every other command that has similar issues to deal with.
Everybody else parses their DefElem list at execution time. I think
you should have the legacy ANALYZE and VERBOSE syntax elements generate
DefElem list members that get examined at execution.
BTW, I see that your "explain refactoring" patch is marked ready
for committer, but is it actually sane to apply it before the other
two?
