Log Message:
Updated archivers/zutils 1.3 to 1.5
---------------------------------- (From NEWS)
Changes in version 1.5:

 zupdate now passes '-q' to zcmp if specified.

 zcat, zgrep and ztest no longer read from standard input more than once
 if '-' is specified multiple times.

 zdiff now uses '_' as separator if both temporary file names are
 otherwise different. For example 'xxx_file.lz' and 'xxx_file.gz'.
