Ian Barwick a2910eded9 Refactor show matrix to handle node IDs correctly. ...

Previously the code assumed repmgr node IDs to be sequential,
which is not guaranteed to be the case. With a non-sequential
list of node IDs, an incorrect node id would be displayed,
and memory accessed beyond the bounds of the matrix array.

The refactored code is considerably less elegant than the original
but will correctly handle a non-sequential sequence of node IDs.
