ruby.c: origarg

Browse Source 
* ruby.c (dladdr_path, ruby_set_argv): add guards for origarg.
  [ruby-core:82272] [Bug #13788]

* ruby.c (proc_options, process_options, ruby_process_options):
  set origarg if not set yet.

* ruby.c (process_options): prefer argv in the argument to origarg
  as program name.

* ruby.c (ruby_sysinit): set origarg only if argc and argv seem
  valid.
