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. [Fix GH-1871] From: Masataka Pocke Kuwabara <kuwabara@pocke.me> git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@63342 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
