Subject: [PATCH] Always move ID comment to end of message (#1362)

Having the comment in the middle of a message causes issues with
Markdown rendering (#1362). Instead, remove all previous identifiers
and re-add the comment at the end of the message.

This change is backwards compatible and will automatically repair
messages generated by a previous version when they are updated.
