String representation of expressions with quotes in non-standard string literals

[pfarndt]

The string representation of an expression that contains quotes " in triple-quoted non-standard string literals (or escaped quotes in quoted non-standard string literals) is not faithfully any more. The resulting text does not represent valid Julia code and cannot be included again. in Julia v1.4

julia> print(:(r = r"""45 " """))
r = r"45 " "

julia> print(:(r = r"45 \" "))
r = r"45 " "

This does not happen for "normal" strings

julia> print(:(r = "45 \" "))
r = "45 \" "

and also used to work in Julia v1.3.1. See also https://discourse.julialang.org/t/string-representation-of-expression/36729/3?u=pfarndt

@JeffBezanson, I don't recall many changes to string literals aside from the recent one you did for multiline string literals. Any possibility that might have affected this?

It's a printing issue; #32423.
