That's right.  And also the lack of the bug number, see below.

That's just my personal preferences of style, as there's always a
judgment call regarding the description of the changes.  We don't have
to agree about that, and if your log message was in the right format,
I probably wouldn't have bothered changing their text.

I can explain my preference: your text described in a very detailed
form something that was acutely visible from the diffs themselves,
whereas my text only describes the motivation, leaving the rest to the
diffs which speak for themselves.

The part about LGTM warnings didn't seem important enough to me: LGTM
is not a compiler, and without a reference to what it is, the text is
a small riddle in itself.  More importantly, I don't think we need any
justification for removing variables initialized to zero and never
changed.

Again, these are my personal preferences, not something we require
from each contributor.  So if you disagree, you can keep your style,
and only adjust the form.

References to bug numbers should always be in the log message, because
that allows an easy way of reading relevant discussions recorded by
the bug tracker.  This _is_ in CONTRIBUTE, btw.

"Bug" here doesn't mean a literal bug, it means an issue recorded by
the bug tracker.

Thanks.
