Advertise the rule screens in the key help

The bottom help still described 4 as "rules" from before the rules list
existed, and never mentioned 5 at all, so the new screen was unreachable
unless you already knew about it.

The transactions line had also outgrown the window: at 137 characters it ran
past the edge of a normal terminal and "q quit" was simply gone. Help now
wraps to the window width instead of being cut off, and that line is shorter.
