Changes in version 0.24:

The option '-C, --directory' is now position-dependent also for diff and
extract. (Reported by Devon Sean McCullough).

Option '--uncompressed' can now be omitted if it can be deduced from the
archive name. (An uncompressed archive name lacks a '.lz' or '.tlz' extension).

The diagnostic shown when a file being archived or an archive being
compressed fails to read, now shows the cause of the failure; end-of-file or
read error.

'-z, --compress' now exits with error status 2 if any input archive is an
empty file.

A failure in the '--diff' test of the testsuite on OS/2 has been fixed.
(Reported by Elbert Pol).
