Its not as interesting as you think. 99% of the compressed data is skipped right over. I just have an odd database file format which interleaves record header information and then LZW compressed data. The only *actual* LZW thing I match is the two byte magic string "\037\235" and then the rest is about the header components. The thing is - re'debug' ends up passing the LZW data right through which is what screws things up.
