Subject: [PATCH] screen_write_copy tried to be clever and clear the line if it
reached the end of the source, but it was wrong and causes problems that are
only showing up now we are more aggressive about skipping redundant screen
updates. Remove the optimization entirely as more trouble than it is worth to
fix (and it'll have to go when BCE is done anyway).
