delete

• (send a-wx:media-edit delete start end scroll-ok?) -> void
      start : small integer
      end = -1 : small integer
      scroll-ok? = #t : boolean

  Deletes the specified range in the buffer. If start is -1, then the starting selection position is used; if end is -1, then only the character preceding start is deleted. If scroll-ok? is not #f and start is the same as the current caret position, then the buffer's view may be scrolled to show the new selection position.
