[Bug-vc-dwim] bug#38934: bug#38934: [PATCH] vc-dwim: die if no one-line summary.

[Karl Berry]

    I like it enough that I've adjusted the many resultant test failures

Thanks much. I admit I totally spaced on thinking about the vcd tests.
(And I'm kind of glad I did, since I probably would have given up. :)

    Here's the merged commit I want to push later today.
    Also adjusted NEWS.

Great. Thanks again. -k
