The other reason to use %r is to get the enclosing quotes in the
displayed message. That reason applies even in cases like this where
the escaping aspect isn't a concern.
And then you make it {!r} so you can use str.format and you complete
the tweak of the string formatting! =) Seriously, though, it wouldn't
hurt to update it to use str.format().
Well, except that {!r} is twice as verbose as %r....
