Inserting an actual line break inside a string literal is equivalent to
writing "\n" inside a single-line string.

If you want a string literal that's multi-line in the source code but
not in its actual value, use the ~ operator, like this:

	// This string doesn't contain any newline characters.
	string str = "blah blah blah "~
		"more more more "~
		"end";

Using ~ explicitly has the nice side-effect that you can indent your
literal nicely, but the indentation spaces are not part of the string's
value, so you can indent freely.
