Sometimes people both write in the exact same section, not touching any of the text elsewhere. When it comes to an edit conflict, though, they are presented with the whole page, which makes it much harder to navigate in.
Change the TwoColConflict special page so that it only puts the section in question into the text editor.
N.B: We can only work on section level, if both people have touched NOTHING but the one section the conflict happened in. All other cases should behave the current way
