I love your report! Interestingly I had already noticed this problem
myself and v3 of the patch fixes the issue. See:
If the maintainer of the robot is reading this, something to improve
about your robot is that it could have noticed v3 of the patch (which
was posted several days before your report) and skipped analyzing v2
of the patch. I'm currently using Change-Ids embedded in my
Message-Id to help automation relate one version of my patches to the
next. Specifically you compare the Message-Id of v2 and v3 of this
Since the last section before the "@changeid" remained constant it
could be assumed that this patch replaced the v2. I know there's not
too much usage of this technique yet, but if only more tools supported
it then maybe more people would use it.
Thanks for your suggestion, the root cause is that the v3 wasn't handled
before this report.
We'll definitely give serious thought to your suggestion.
