    gutterrendererchunk: Fix line number display in short file (bgo#760978)
    
    If the number of lines in the file was fewer than 100,
    recalculate_size never set the GutterRenderer size because the digit
    count was always correct. Now we set the number of digits to zero,
    forcing an initial size calculation and setting.
