If you look at "git log" output, you would notice that people write
something like

	Helped-by: Michael Haggerty <[email-masked]>

before your S-o-b: line for a case like this.

We can see that you are replacing tmpname with pack_tmp_name in
warning without you writing on the subject line.  The commit log is
where you explain *why* that change is the right thing to do.  And
that is totally lacking in this message.
