Ick. I really hate using shell metacharacters that need quoting
(especially "!", which even gets expanded inside double-quotes). But as
long as it's an alias, I guess people who care can use --grep-not.

We could use unadorned "--or" and "--and", though we should perhaps stop
and think whether taking those basic operators will block future use
that matches the current "--not" more.

Right now, "git log a b" is what I would expect "git log a --or b" to
do. I guess "git log a --and b" would be "git log $(git merge-base a
b)". So maybe it is not worth reserving them for the future, since what
they would (probably) accomplish is easy to do now.
