Hi there,

Not really a bug per se but rather a feature request. Gzip command on Debian Squeeze should not ouput any message when invoked with no arguments and -q option has been specified -- e.g. on FreeBSD, -q option *does* suppress all warnings and gzip keeps its mouth shut even if exit status is greater than 0 (!?) Before submitting this bug report, I downloaded gzip 1.4 on my Debian system and compiled it but got the same behavior as the installed 1.3.12 version.

IMHO, Gzip should work the same across operating systems for the following command:

$ find /my/stuff -mtime +7 -name '*.csv' -print0 | xargs -0 gzip -q

which should fail silently when no files could match the search criterias.

Thank you.
