Translate Core Labels

The labels for the "Title" and "Body" fields (whatever you decide to label them for a given content type) do not get translated in node.module or node.pages.inc. This tiny module takes care of that, passing the labels through t().

According to the developer of the i18n module, a future release of that module will address this issue, making this very simple module unnecessary (see http://drupal.org/node/149349#comment-1181176).
