REPL pretty-printed output does not distinguish between escape sequences and escaped escape sequences

See original GitHub issue

These strings are different:

scala> "\n" 
val res0: String = "\n"
scala> "\\n"

Dotty isn’t going to inline anything compiled by Scala 2, including the standard library. Running our standard benchmarks won’t help you here since we don’t benchmark the REPL. In any case, I doubt this is going to make any perceivable difference in performance.

I think this could be fixed by simply adding the backslash as a special case to be escaped in library/src/dotty/Show.scala for stringShow and charShow.
