REPL should display multi-line strings in multiple lines

[JJtan2002]

When displaying a multi-line string, the REPL is showing '\n' instead of newlines. The REPL should display each line separately, preserving the formatting of the input.

An example with multi-line strings in Python §1.

Another example with template literals in Source §1.

I'd say this is a feature, not a bug. The first argument of display shows the value as if it were a value expression in a program.

The second argument of display is displayed in the way you are requesting. Instead of the change proposed here, I have an alternative proposal: #1664

Closing this in favor of #1664
