This is now fixed on the master branch. The situation where buffer
changes happen in a window whose start point is on a continuation line
was mishandled by code that never expected to find itself in this
situation. After the fix, the recipe leaves point at the end of line
15, in a window that displays that single line at its top.
Thanks for the easy to reproduce recipe.
