[5.0.x] Issues with some mpirun arguments (map-by, output-filename, indentation)

[devreal]

• Specifying the --map-by argument leads to an error:

$ mpirun -N 1 -n 2 --rank-by core  --map-by node hostname
--------------------------------------------------------------------------
When resolving deprecated command line options, the result generated
too many directives for the target option:

  Command line option: map-by
  Initial value: ��,
  Deprecated option: N ppr:1:node

Please correct the command line and try again.
--------------------------------------------------------------------------

Note that the Initial value shows a corrupted string. Overall, the error message does not provide any useful information and I don't see why --map-by node should not work.

• The --output-filename seems to work (with some heavy extension of the filename) but doesn't appear in the help output.

• There is also a bunch of indentation missing, e.g.:

   --default-hostfile <arg0>         Provide a default hostfile
-H|--host <arg0>                     List of hosts to invoke processes on

Just FYI: -N 1 resolves to a --map-by ppr:1:node directive. Thus, you wind up with two invocations of the --map-by cmd line option, and that's the error.

@devreal is this resolved in your eyes? Can you try with the latest main (we did a prte/pmix submodule update this morning).

Closing due to inaction. Please reopen if this is still an issue with latest v5.0.x
