Upon successful run gyb outputs a blank line

[laacz]

I run GYB regularily from the cron. Each time it generates an empty line to the stderr. This causes a regular notification to the email with a lone newline.

Full steps to reproduce the issue:

~/bin/gyb/gyb --email $EMAIL --action backup --search "newer_than:7d" >/dev/null

Expected outcome (what are you trying to do?):

No output being generated, if the command completes successfully.

Actual outcome (what errors or bad behavior do you see instead?):

A newline is printed.
