Thanks for enduring three iterations for a single-liner.  This
versio will show nicely in "git log -p" output ;-)

In case anybody is wondering, that "Helped-by: notifications@github"
was merely because I said "this change makes sense, care to send it
over to us at git@vger?" from github UI on Ariel's commit.  I do not
deserve helped-by for merely encouraging participation.

Will queue.  Thanks again.
