Comment 47 for bug 250820

Since it would take quite a bit of effort to put the synthesized trailer line after the pertinent changelog section, Colin was kind enough to make the following suggestion:

"if you can't put the synthesised trailer line in the right place, it would be better to format it as "Key: value" lines rather than pretending it's a changelog trailer"

.. and (barring any objections) that's the format that will be implemented.
