Defect/Bug Report

See also #460 for additional context. The caftan script requires -np and <N_IMAGES> as the first and second argument (when not passing --show. Worse yet, --show gives no indication that there will be problems if you add an additional argument to caftan ahead of -np <N>.

• OpenCoarrays Version: All recent versions
• Fortran Compiler: GFortran 7/8
• C compiler used for building lib: GCC
• Installation method: doesn't matter
• Output of uname -a: Linux on Travis-CI
• MPI library being used: OpenMPI
• Machine architecture and number of physical cores: 2VPU
• Version of CMake: Doesn't matter

Observed Behavior

Users pass --oversubscribe (required for OpenMPI) ahead of -np 5 etc. and things blow up

Expected Behavior

Parse options with arguments correctly. This will make the code cleaner and more generic too.

Steps to Reproduce

cafrun --show --oversubscribe -np 4 FORTRAN/transpose-coarray 10 1024 32
cafrun --oversubscribe -np 4 FORTRAN/transpose-coarray 10 1024 32

Put @zbeekman in the corner of shell scripting shame
