Comment 4 for bug 493835

just to be sure : what we want here is that the Task.add_tag() method add the tag to the text of the task if that tag is not present. Is that right?

I see two possible approaches :

1) We modify the text of a task when adding a tag.

2) When we open a task with the editor, we add tags that are not in the text.

I don't know which one would be more appropriate. What do you think?
