[petsc-users] Not displaying petsc options with -help

[Barry Smith]

   Change the value of PetscHelpPrintf() to do nothing before PetscInitialize() and then change it PetscHelpPrintfDefault() just around your options.

   I have fixed up the manual page in https://gitlab.com/petsc/petsc/-/merge_requests/3553

    But are you sure you want to do this? Even -ksp_monitor etc will no longer produce help messages which users may want.

When running the application with “-help” option all the application and PETSc options get displayed. Is there a way to suppress displaying PETSc options, but only display the application options.
