plsetopt("-h",NULL) exits the process and doesn't even show any
help. The -v option does the same thing (i.e. exits the process
without any output). I think this could be fixed relatively easily
and without any negative impact by changing opt_h and opt_v (in src/
plargs.c) to return 0 (instead of the exit-inducing 2) if mode_quiet
is enabled (else return the exit-inducing 2 as it does now).
