error! and debug! escape single quotes strangely

[catamorphism]

fn main() {
    error!("It's time for dinner!");
}

prints

rust: ~"It\'s time for dinner!"

io::println prints the correct output. Not a big deal, just a little strange.

It's even worse now that it passes its argument to fmt!:

rust: ~"\"It\\\'s time for dinner!\""

Huh, it's not instantly godawful with format!

rusti> format!("It's time for dinner!")
~"It\'s time for dinner!"

Agreed though that it still shouldn't escape the single quote.

I believe that this is closed with a combination of #9005, #9046, and format!/error2!.

I'm going to close this because there's not really an issue to track the transition from error => error2, but it's high on my todo list as soon as a snapshot becomes available.
