When splitting a long line across an operator, I've always preferred
to put the operator at the end, because it makes it obvious that the
line isn't finished. Not just for the Ruby interpreter, but for the
user as well. Even in Java, I prefer to write:

int val = Foo.someLongThing() +
    Bar.otherLongThing();

even though Sun's official Java style guide dictates putting the + at
the start of the second line.
