Backport #4385

=begin 
  
  I'm found a strange behavior of YAML in ruby 1.8.7 on simple string: 
 
  ruby-1.8.7-p330 :002 > require 'yaml' 
   => true  
  ruby-1.8.7-p330 :003 > YAML::load("\n {\n}".to_yaml) 
  ArgumentError: syntax error on line 3, col 0: `}' 
 	 from /Users/sand/.rvm/rubies/ruby-1.8.7-p330/lib/ruby/1.8/yaml.rb:133:in `load' 
 	 from /Users/sand/.rvm/rubies/ruby-1.8.7-p330/lib/ruby/1.8/yaml.rb:133:in `load' 
 	 from (irb):3 
 
 
  In ruby 1.9.2 seems to be all fine: 
 
  ruby-1.9.2-head :011 >     require 'yaml' 
   => true  
  ruby-1.9.2-head :012 > YAML::load("\n {\n}".to_yaml) 
   => "\n {\n}"  
 
 
  Encoding results: 
 
  ruby-1.9.2-head :002 > "\n {\n}".to_yaml 
   => "--- \"\\n {\\n\\\n}\"\n"  
 
  ruby-1.8.7-p330 :002 > "\n {\n}".to_yaml 
   => "--- |-\n\n {\n}\n"  
 
 
 
 
  I'm check this on Mac OS and FreeBSD: 
 
  Darwin 10.6.0 Darwin Kernel Version 10.6.0: Wed Nov 10 18:13:17 PST 2010; root:xnu-1504.9.26~3/RELEASE_I386 i386 
  FreeBSD 8.0-STABLE FreeBSD 8.0-STABLE
