 Wordpress core function "language_attributes()" is returning by example
 'en_US' and should return 'en-US'.
 This could be important when crawlers are parsing and indexing pages
 saving the parsed language found in that element.

 Following w3c specification of html language attribute we can confirm
 that.

 HTML 4.0 lang spec:
 http://www.w3.org/TR/html4/struct/dirlang.html

 HTML 4.1 lang spec:
