Comment (by josef):
On the whole I think your new set of proposed changes will make things
much more intuitive, especially bullets two and four. I'm stumped by the
status quo every time I try to use rewrite rules.
As for bullet five, I'd prefer -fenable-rewrite-rules, simply because it
has a more natural reverse: -fdisable-rewrite-rules. -fdon't-use-rewrite-
rules doesn't feel quite right.
