    Description

      In a chained replication scenario, a node will update it's own local.slaves collection. This is indicated in the output of mongostat as a local update, while other update operations are described as from replication. This is shown with the usual shorthand - two numbers separated by a pipe character. The issue is, only those rows in the output that have a local update are displayed this way. All other rows are shown as a single number:

      *20   2771      1     *0      17    38|0       0   656g  1313g   164g      0  test:2.6%          0       1|0     2|0   952k   913k   667 testRS  SEC   03:48:33
      *30   2830    1|1     *0      23    55|0       1   656g  1313g   164g      0  test:0.2%          0       0|0     0|0   973k   946k   667 testRS  SEC   03:48:34
      *16   3050      1     *0      13    46|0       0   656g  1313g   164g      0  test:2.6%          0       0|0     3|0     1m     1m   667 testRS  SEC   03:48:35
      *22   2996      1     *0      18    56|0       0   656g  1313g   164g      0  test:0.2%          0       0|0     2|0     1m     1m   667 testRS  SEC   03:48:36
      *24   3141      1     *0      20    41|0       0   656g  1313g   164g      0  test:3.0%          0       0|0     2|0     1m     1m   667 testRS  SEC   03:48:37
       *8   2950      1     *0       9    33|0       0   656g  1313g   164g      0  test:0.2%          0       0|0     0|0     1m     1m   667 testRS  SEC   03:48:38

      This makes the output inconsistent and hard to read.

      Elsewhere in the output, the pipe delimiter is used on every line (for example, in the command column).
