That behavior is correct an in accordance with the standard.  Check out:
        http://www.opengroup.org/onlinepubs/9699919799/utilities/read.html

A script that doesn't want that behavior should be using the -r option
to 'read'...but's there's a bug in our sh: the -r option only disables
the handling of backslash at EOL and not embedded in the line.  Oops.
Can you file a bug for this with sendbug?
