[TUHS] 10 Edition pack and unpack available

[Arnold Robbins via TUHS]

Hi All.

I recently had need to uncompress a file that was compressed with
the original Unix pack(1) command.

The code from v10 actually compiled, but with LOTS of warnings.

I have cleaned the code up somewhat and made it available
on GitHub: https://github.com/arnoldrobbins/V10-pack-unpack. It now
compiles without without complaint.

Enjoy,

Arnold
