I read meta is used for reporting bugs in the StackExchange software. This is just a cosmetic thing:
When you add a comment to an answer starting with
@name (with the name of the answerer),
@name is removed as the answerer receives a notice about your comment anyhow. But when you click on edit and add it again the comment is marked edited while it's effectively not.
The question is: Is this find too lame to be reported?
