Code review comment for ~bryce/ubuntu/+source/apache2:sru-lp1832182-graceful-groovy

Thanks for the review.

It's a fair point that in an SRU context that changes to output are effectively behavioral changes. However, I'm not sure it's worth worrying about since a) this affects just the 'graceful' command which had been a bit broken to begin with (thus the bug), and b) the new output is consistent with the output from the 'start' command. People who had been avoiding 'graceful' due to the misbehavior likely will already be dealing with the status output from the 'start' command so if due to this fix they start using graceful they may find the lack of status output weird.

That said, I do find it a bit odd that the start command outputs to stdout rather than stderr, but this seems semi-consistent with similar code. Other places in the code do emit to stderr and I don't know if this is intentional or a discrepancy. In any case, I wanted to make this a minimal fix so am keeping similar to existing code style and not fixing up inconsistencies in the rest of the script, tho I am quite tempted... Maybe someday.
