Modify datatest parse to eat whitespace when line continuation is in effect

Previously the parsed string would look as follows. You would get this on a failed self test.
Key: 0000000000000000
    0000000000000000
        0000000000000000
            0000000000000000

The new behavior eats the leading whitespace, so the key is reported as:
Key: 0000000000000000000000000000000000000000000000000000000000000000
