Tomas Hoger 487913d9a6 Slightly improve LZW_CLEAR handling.
* src/lzw/ftzopen.c (ft_lzwstate_io) <FT_LZW_PHASE_CODE>:
Ensure that subsequent (modulo garbage byte(s)) LZW_CLEAR codes are
handled as clear codes.  This also re-sets old_code and old_char to
predictable values, which is a little better than using `random'
ones if the code following LZW_CLEAR is invalid.
