On my system, ruby 1.8.2 (2004-12-25) [i386-mswin32], the first two
seemed to work:

>> YAML.load("abc\r\n".to_yaml)
=> "abc\r\n"
>> YAML.load("\r\n".to_yaml)
=> "\r\n"

But the third didn't:

>> YAML.load("\n".to_yaml)
=> " "

I guess if all else fails you could:

>> CGI.unescape(YAML.load(CGI.escape("\n").to_yaml))
=> "\n"
