    Use cursor position change rather than manual trigger for diff recalc
    
    Manually triggering a diff-change when a buffer was set editable was
    problematic in cases where we're loading a new file. In this situation,
    the current diff chunk was set to an invalid index in the newly-reset
    differ, as the current chunk isn't invalidated.
    
    This commit forces the diff-change recalculation by instead forcing a
    cursor chunk change, which is how we do this elsewhere in the
    codebase.
