  New Revision: 66692

  https://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=revision&revision=66692

  Log:
    .travis.yml: enforce -w in invoke_ruby as well
    
    actually current test-all does not fail with RUN_OPTS="-w".
    
    and chkbuild seems to use RUBYOPT="-w"
    https://github.com/ruby/chkbuild/blob/bad4681c30e71f132cdd80f324d4b8f132f6582c/chkbuild/ruby.rb#L605
