QuotedPrintableCodec does not support soft line break per the 'quoted-printable' example on Wikipedia

Writing a unit test I discovered that the example Wikipedia uses for quoted-printable data does not decode but instead throws an exception.
Their example is here: http://en.wikipedia.org/wiki/Quoted-printable#Example

test:

String qpdata = "If you believe that truth=3Dbeauty, then surely=20=\r\n" +
"mathematics is the most beautiful branch of philosophy.";

String expected = "If you believe that truth=beauty, then surely " +
"mathematics is the most beautiful branch of philosophy.";

assertEquals( expected, new QuotedPrintableCodec().decode(qpdata) );

I suppose I could fix if you like but currently I'm not a registered developer.
