Postponing the Bundler merge.

  I faced a big issue about Bundler with ruby core.
  I have no time to resolve it issue before 2.5 final release.

-    # Runs the install procedures for a specific Gemfile.
-    #
-    # Firstly, this method will check to see if `Bundler.bundle_path` exists
-    # and if not then Bundler will create the directory. This is usually the same
-    # location as RubyGems which typically is the `~/.gem` directory
-    # unless other specified.
-    #
-    # Secondly, it checks if Bundler has been configured to be "frozen".
-    # Frozen ensures that the Gemfile and the Gemfile.lock file are matching.
-    # This stops a situation where a developer may update the Gemfile but may not run
-    # `bundle install`, which leads to the Gemfile.lock file not being correctly updated.
-    # If this file is not correctly updated then any other developer running
-    # `bundle install` will potentially not install the correct gems.
-    #
-    # Thirdly, Bundler checks if there are any dependencies specified in the Gemfile.
-    # If there are no dependencies specified then Bundler returns a warning message stating
-    # so and this method returns.
-    #
-    # Fourthly, Bundler checks if the Gemfile.lock exists, and if so
-    # then proceeds to set up a definition based on the Gemfile and the Gemfile.lock.
-    # During this step Bundler will also download information about any new gems
-    # that are not in the Gemfile.lock and resolve any dependencies if needed.
-    #
-    # Fifthly, Bundler resolves the dependencies either through a cache of gems or by remote.
-    # This then leads into the gems being installed, along with stubs for their executables,
-    # but only if the --binstubs option has been passed or Bundler.options[:bin] has been set
-    # earlier.
-    #
-    # Sixthly, a new Gemfile.lock is created from the installed gems to ensure that the next time
-    # that a user runs `bundle install` they will receive any updates from this process.
-    #
-    # Finally, if the user has specified the standalone flag, Bundler will generate the needed
-    # require paths and save them in a `setup.rb` file. See `bundle standalone --help` for more
-    # information.
