----------------------------------------

https://bugs.ruby-lang.org/issues/12664#change-60877

* Author: Petr Chalupa
* Status: Closed
* Priority: Normal
* Assignee: Akira Tanaka
----------------------------------------
With following addition

~~~ ruby
class String
  def pretty_print(q)
    lines = self.lines
    if lines.size > 1
      q.group(0, '', '') do
        q.seplist(lines, lambda { q.text ' +'; q.breakable }) do |v|
          q.pp v
        end
      end
    else
      q.text inspect
    end
  end
end
~~~

a multiline String will print as follows

~~~ text
[9] pry(main)> pp "bundler.rb"=> "module Bundler\n  BundlerError = Class.new(Exception)\n  def self.setup\n  end\nend\n"
{"bundler.rb"=>
  "module Bundler\n" +
  "  BundlerError = Class.new(Exception)\n" +
  "  def self.setup\n" +
  "  end\n" +
  "end\n"}
~~~
