No, I don't think so. All the complaints until now were about Diff mode and related modes, and we made the relevant faces extend a few hours ago. At least in one case, this change allowed to _remove_ some kludgey code (in info.el). And doing this the opposite way makes no sense to me, it's in effect the same as removing the feature. > This change breaks a lot of out-of-tree code. No, it doesn't break any code. It changes how display looks in some cases, so people are surprised at first. For this particular bug report, why would someone expect the overlay's color to extend to the end of the line instead of affecting only the text that the overlay covers?
