Proposal: multiline should be documented inside REPL

I eventually found the Ctrl-V answer in StackOverflow, but not before I'd used the REPL for about 2 weeks thinking that multiline was broken in the REPL. Also, while StackOverflow told me to use Ctrl-V to enter multiline mode, it didn't mention to use that keycode to exit. So, as a Unix user, I hit Ctrl-D and the REPL quit. It would be nice if the REPL told people about Ctrl-V to enter and exit multiline mode. Also, it would be nice if it told people about .help.
