Post #1444910

@wrog This seems familiar, but I'm not wholly sure why. It is binary 01111110 and as such really did show up in some line noise contexts that favored such a thing (it's similar to 11111111). It's also used by vi to mark nonexistent lines at the end of the file; Bill wanted it to be something other than just nothing on that screen line, for specificity of feedback to the user. @kentpitman @ramin_hal9001 @screwlisp @cdegroot
