tor_bootstrap_progress should echo 0 if no matching log line is found
Originally created by @intrigeri on #8257 (Redmine)
On a (one month old) feature/jessie build, I see:
19:48:39 amnesia nm-dispatcher[2228]: /etc/NetworkManager/dispatcher.d/20-time.sh: 204: [: Illegal number:
19:48:48.000 [notice] Bootstrapped 0%: Starting
Looks like tor_bootstrap_progress
should return (really, echo) 0 if
the grep | tail | sed
pipeline returns nothing.
