function _diff_module_invoke_all in Diff 7.2

Same name and namespace in other branches

1. 6.2 diff.pages.inc \_diff_module_invoke_all()

Helper function to invoke hook_diff in all enabled modules that implement it.

Don't use module_invoke_all() since if date.module is enabled will clash with PHP 5.3's date_diff() function.

@todo figure out any else possible solution but not workaround. @link http://drupal.org/node/639320
