Actually, it doesn't -- you can't compress a .Z very well.  What I think you're 
getting at is that, since the source data has a lot of redundancy *and* is 
human parsable, it can be reconstructed more easily in the case of mangled data.

You changed only one bit, which changed one code into another.  This is a 
reversable transform.  I would suggest REMOVING one bit -- it is still a 
single-bit error, but you will see the entire file become corrupt all the way 
down the line.
