Clarify the meaning and usage of newline and carriage return codes

[thezerobit]

The spec defines whitespace as the space or tab characters, not newlines and makes absolutely no reference to Windows line endings. This means that keys may contain newlines, "Keys start with the first character that isn't whitespace or [ and end with the last non-whitespace character before the equals sign. Keys cannot contain a # character." There is nothing here that implies that a newline character can't be used. I doubt this is intended.

Check out #264. Let me know if that clarifies everything.
