LOGNORMALIZER::CHANGED:: when using '-V' flag, return 0 (zero) when program exits

[frikilax]

Description

When printing lognormalizer's version through its '-V' flag, the return code is not zero, that return code is counter intuitive and prevents using the command in scripts and/or CI/CD frameworks

Changed

• return zero when '-V' flag is detected after printing the version number, instead of 1

oops... that sounds indeed bad.

I would say this does not case a real backwards-compatibilty issue as the tool itself is not used that often. @davidelang what do you think (we are talking about the stand-alone tool, not the rsyslog integration)?

sounds like a mistake, and one that it's very unlikely that anyone is going to depend on, so I would say it's reasonable to fix it. David Lang
