ARGV is empty inside action block

[crawlik]

Looks like latest gli 2.0.0 regressed by making ARGV empty after command line parsing

command :test do |c|
  p ARGV => ["-g", "v1,v2", "test"]
  c.action do |global_options,options,args|
    p ARGV => []
  end
end

Noticed that ARGV is cloned in parse_options but clone is never used after that. I assume args_clone should be used as an input by parsers so ARGV value doesn't change.

 def parse_options(args) # :nodoc:
      args_clone = args.clone

Hmm, I hadn't considered that anyone would be using ARGV directly; args,
passed to the action block should be used instead, but if it's no effort
to preserve ARGV, I might as well.

As a stopgap, you could do

exit run(ARGV.clone)

in your bin file.

I have some code that relies on ARGV in order to get the original command line as it passed by shell for spawning parallel processes with it minus some global options. Plus I think people would agree that global ARGV should not change under any circumstances because it effectively changes starting state of the process.

exit run(ARGV.clone) # this workaround works just fine

Thanks
