Please tell me if the feature is ready > to land on master, or if further improvements are needed. Thanks. I think the code is ready to be merged, but what about the documentation? The branch currently removes all traces of the facilities we previously documented as possible remedies for poor performance in these cases. However, we do know that in some situations redisplay and related commands are still very slow. The NEWS entry on the branch does say that font-lock is one reason for the slowdown. So at least that part should be in the manual, perhaps in the form of a shorter description of so-long mode (because one thing it does is disable font-lock). We can remove that later, if and when these problems and any others we find are also resolved. IOW, I think we still don't have enough data and experience to decide that all those other measures will never be needed, so maybe it is too early to delete their docs.
