It has all to do with a string going over two lines and hence the line
terminator is part of the string.   If you close the string on the first line

At least the newer version of the parser allows for embedded newline characters.

This is a consequence of a change described in NEWS to allow 
multi-line *strings*.

The newline is truncated, as expected.
So the new feature of multiline strings is great, isn't it?
