Release Notes: A manual page that uses the man macro package was added. The README file describes the compressed output and why there is only one exit status for all types of errors. A more portable Makefile was created. A little code was cleaned up.
Release Notes: A class of valid bz2 files the multiple-workers decompressor (MWD) possibly refuses has been described in the Bugs section of the README. By concatenating empty bzip2 streams (each having a length of 14 bytes) and optionally inserting such a sequence before, after, or between non-empty bzip2 streams, the size of the input block that unavoidably contains an entire bzip2 block header can be increased without bound. This invalidates the assumption the MWD is based on. However, neither bzip2 nor lbzip2 creates such files, and bz2 file sets that do defeat the MWD when catenated should be rare.
