HardPressed LZSS problem

[fadden@hkn.EECS.Berkeley.EDU (Andy McFadden)]

Every once in a while, somebody has posted about having a problem with
HP + LZSS eating their files.  Well, it turns out that if the planets
are aligned correctly, LZSS can eat files.  This bug has existed since
HP v1.0.

The fix is to replace the LZSS module with a new one.  Once I verify that
I haven't introduced any *new* problems with this (trivial) fix, I'll
upload the new module.

I'll also include the new AHuff module (which had a buggy decoder... you
might not be able to uncompress some files, but they wouldn't have been
damaged), which is part of the v1.0.2 update.  The v1.0.2 update consists
simply of the ahuff module and a new version of the INIT with a bug fix
and a minor display hack, and ought to be available from WestCode now.

(The bug fix was a problem appending to compressed files.  About the only
place this happens is when you do "cat >> compressed_file" under GNO.)
