Like Giorgios, I think it's nice what you're trying to do here, but I don't
think making it this long is very effective. Trying to describe every little
corner case of update's behavior just means people won't read it all or get
scared of using it. Let's instead give people an idea of what the purpose is
(and what other commands could be used instead) and what the options are.

Cheers,
