This actually only happens if you surround the anchor by empty

This is now fixed, the invisible targets are added as empty anchors
to the headline that must be directly before or after the anchor.

Fixed as well, thanks.  I guess when I implemented this a long time
ago, I did not realize that empty anchors are allowed.
