When a quoted-printable message is incorrectly terminated at EOF:

    p;</td>=0A=0A        <td width=3D"49%">&nbsp;</td>=0A      </tr>=0A    </tb=
    ody>=0A  </table>=0A</body>=0A</html>=0A=
    --=_mixed 002D08B5C1257475_=--

(missing newline before the separator) qp-decode barfs:

Error: line 758: '^@' is something other than line break or hex digit after = in quoted-printable encoding

and continues to read into the invalid buffer contents.

IMHO, if EOF is encountered, it simply should stop processing and
issue no error message:

  		fprintf(stderr, "Error: line %d: '%c' is something other than line break or hex digit after = in quoted-printable encoding\n", lineno, *stop);

  		putchar(*stop);
