This PR was originally to fix the E_DEPRECATED that was thrown do to our usage of the e modifier in the JFilterInput::_decode method, but I saw that a fix for it has been merged. However, this fix utilizes anonymous functions, something that doesn't exist in PHP 5.2. Since Joomla 2.5 has a minimum requirement of 5.2, we cannot use anonymous functions in this case.
The original patch was merged on September 12th here - 341512f - thankfully we haven't had a release since then...
