Update reference.md: string literals section

Remove the name "multi-line string literal" since the rule appears to affect each line-break individually rather than the whole string literal. Re-word, and remove the stray reference to raw strings.

 A _string literal_ is a sequence of any Unicode characters enclosed within two
 `U+0022` (double-quote) characters, with the exception of `U+0022` itself,

-A multi-line string literal may be defined by terminating each line with a
-`U+005C` character (`\`) immediately before the newline. This causes the
-`U+005C` character, the newline, and all whitespace at the beginning of the

+Line-break characters are allowed in string literals. Normally they represent
+themselves (i.e. no translation), but as a special exception, when a `U+005C`
+character (`\`) occurs immediately before the newline, the `U+005C` character,
+the newline, and all whitespace at the beginning of the next line are ignored.
+Thus `a` and `b` are equal:
 
 ```rust
 let a = "foobar";
