Oh absolutely.  Quite often the changelog body contains no information
which wasn't in the title, so there's no need for a body.

I think what triggered this was a patch from Mark which had no
changelog and which had me sitting there wondering wtf it does, whether
we need it in 2.6.29, whether we need it in 2.6.28.x and earlier and me
not having the foggiest clue then getting grumpy.
