Changes in version 1.4:
Changes in version 1.5:
The option "--format" has been renamed to "-O, --force-format".
zupdate now passes '-q' to zcmp if specified.
Option "-M, --format=<list>" now restricts automatic search to the
formats listed in the comma-separated <list>. This change introduces a
backward incompatibility with previous versions of zutils.
zcat, zgrep and ztest no longer read from standard input more than once
if '-' is specified multiple times.
If the pattern begins with "-", zgrep now prepends "-e" before passing
it to grep. ('zgrep -- -pattern file' now works as expected).
The targets "install-compress", "install-strip-compress",
"install-info-compress" and "install-man-compress" have been added to
the Makefile.
zdiff now uses '_' as separator if both temporary file names are
otherwise different. For example 'xxx_file.lz' and 'xxx_file.gz'.
