Sure it has, but a bit limited. When it reads a \, the next character is
read as is and the \ discarded. Unfortunately, newline is an exception
-- it is discarded too. I've just tried it and it does not seem all that
useful. It can only quote the separation character when reading multiple
fields.

Proper quotation can do a little more, actualy. But it still strips
trailing whitespace. Unfortunately, all of it, not just one \n. This can
be fixed using the ${foo%x} syntax, but is a bit cumbersome.
