OK, my tests are all successful until now. Speed is relatively the same,
doesn't matter whether the compressed file is a 4KB text file, or a 50MB
avi movie :) Unfortunately there is still overhead as compared to the HE
case, speed being somewhat 20% slower. I am still not 100% whether this
would hold true in all cases and if I am wrong, it might happen that for
some archives we can get false negatives.

I am not yet 100% convinced I am correct yet though. The approach is based
on 2 assumptions, first one can easily be proved, the second one is related
to the LZ algorithm and I cannot yet prove what I check is safe and can't
occur in a valid LZ stream.
