<Krenair> Move the cursor to the end of a line before the start of a new section header, delete, enter, enter, up, delete, type a random character. <James_F> Backwards delete or forwards delete? <Krenair> Um. The delete next to 'Home' and 'End' <Krenair> not backspace <James_F> Forwards, then. :-) <James_F> Whee, snowmen. <James_F> I blame edsanders. <Krenair> observed on http://en.wikipedia.org/wiki/Hippeastrum_calyptratum, depending on what random character you try (I hit 'f'), stuff breaks in a difficult to explain but quite obvious <Krenair> especially if you do it twice to the same document <James_F> So the first thing that happens is that the cursor ends up outside of the document. <James_F> Which is Bad™. <James_F> Everything breaking after this is non-deterministic, but definitely also Bad™.
If you put the cursor at the end of a paragraph and press Delete, the cursor will go to the top left corner of the surface (range (0,0)). However, if the next thing after the cursor is not a paragraph (but e.g. a heading) this doesn't happen. Once the cursor is at (0,0) and you start typing, things break completely.
