  • SR-11215 REPL doesn't understand multiline raw string literals

Issue Description:

$ swift
Welcome to Apple Swift version 4.0 (swiftlang-900.0.43 clang-900.0.22.8). Type :help for assistance.
  1> let s = """
error: repl.swift:1:9: error: unterminated string literal
let s = """
        ^

The REPL knows how to handle multiline array literals, so it ought to be able to handle unterminated triple quotes as well.

Yes, if you press return right after the """, you will get exactly the same error message. But Swift REPL allows you to press down arrow when you enter the code. This code below should work for you.

let s = """(press down arrow)
this is the first line(press down arrow)
this is the second line(press down arrow)
"""(press return)

In Swift 5.0.1 the REPL seems to understand multiline string literals just fine, but raw multiline string literals are still broken.
