Press This introduced a PHP 5.1 function

[DD32]

htmlspecialchars_decode() is only available in PHP 5.1+: ​http://trac.wordpress.org/browser/trunk/wp-admin/press-this.php#L554 appears to have been added in [9787] which means WP 2.7 is affected

A similar case where this would've been useful is #6992 perhaps a compat function should be added?

(In [10236]) htmlspecialchars_decode() for php versions less than 5.1, props sivel, fixes #8679
