Yeah, it's an accidental double click thing. On closer examination it looks like I read the diffs backwards. So it's actually a case that the second, not the first, revision contains the tildes because that's the text it's trying to add, while the complete and stored version contains the signature. Because the actual post is identical, only the signature and tildes are highlighted red in the EC diff that it presents to you at the end.
