Changes in version 1.0:

The new option "--format" has been added to all utilities.

Zgrep no more prefixes the file name to the output by default when
searching one file and "--recursive" has not been selected.

The output of "zgrep -L" has been fixed (it behaved like "zgrep -l").

A deadlock in zcmp, which happens when the "-n" option is used, has been
fixed.

Decompressors are now invoked without the "-q" option except if
explicitly requested, as some simplified implementations do not accept
it.

Quote characters in messages have been changed as advised by GNU Coding
Standards.

"configure" now accepts options with a separate argument.

Configure option "--datadir" has been renamed to "--datarootdir" to
follow GNU Standards.

The target "install-bin" has been added to the Makefile.

Information has been added to the INSTALL file about how to install
zutils along with GNU gzip.
