For a small change like this, the above is sufficient as all the
necessary things are described, but for future reference, we prefer
to explain things in this order:

 - Give an observation on how the current system works in the
   present tense (so no need to say "Currently X is Y", or
   "Previously X was Y" to describe the state before your change;
   just "X is Y" is enough), and discuss what you perceive as a
   problem in it.

 - Propose a solution (optional---often, problem description
   trivially leads to an obvious solution in reader's minds).

 - Give commands to somebody editing the codebase to "make it so",
   instead of saying "This commit does X".

You are going backwards ;-).

Will queue.  Thanks (and thanks for all the reviewers who helped
polish the draft to get to this v2).
