Subject: [PATCH] cg-diff fixed to work with BSD xargs
Message-ID: <11253960093915-git-send-email-martin@catalyst.net.nz>

Calls to cg-diff without filename parameters were dependent on GNU xargs
traits. BSD xargs is hardcoded to do --no-run-if-empty -- so if the filter
is effectively empty we avoid calling xargs.
