Thanks for the report, but the behavior you are seeing is documented as
intentional.  This is so that a newline in a filename is unambiguously
parseable via an escape sequence (the leading \ tells you that escape
sequences will be present).  As the manual mentions that this is
intentional behavior, I'm closing this as not a bug, but feel free to
respond with further comments.
