fmt-merge-message: add empty line between tag and signature verification
When adding the information from a tag, put an empty line between the message of the tag and the commented-out signature verification information.
At least for the kernel workflow, I often end up re-formatting the message that people send me in the tag data. In that situation, putting the tag message and the tag signature verification back-to-back then means that normal editor "reflow parapgraph" command will get confused and think that the signature is a continuation of the last message paragraph.
So I always end up having to first add an empty line, and then go back and reflow the last paragraph. Let's just do it in git directly.
The extra vertical space also makes the verification visually stand out more from the user-supplied message, so it looks a bit more readable to me too, but that may be just an odd personal preference.
