vim-patch:9.1.0617: Cursor moves beyond first line of folded end of buffer (#29859)

Browse Source 
Problem:  Cursor moves beyond start of a folded range at the end of a buffer.
Solution: Move cursor to start of fold when going beyond end of buffer.
          Check that cursor moved to detect FAIL in outer cursor function.
          (Luuk van Baal)
