nobu 2ad7fb6dc1 optparse: Suppress warnings ... Ruby warns "instance variable `@version` not initialized" for optparse when it receives `--version` option. `test.rb` ```ruby require 'optparse' Version = '1' OptionParser.new.parse(ARGV) ``` ``` $ ruby -w test.rb --version /home/pocke/.rbenv/versions/2.5.1/lib/ruby/2.5.0/optparse.rb:1168: warning: instance variable @version not initialized /home/pocke/.rbenv/versions/2.5.1/lib/ruby/2.5.0/optparse.rb:1175: warning: instance variable @release not initialized test 1 ``` This change will suppress the warnings.
