TYPO3 Core

Content elements with language setting [All] (sys_language_uid = 1) are not rendered in the frontend and are not shown in the backend Web>Page view.
This has been reported in several bulletin boards since about two years, but the problem still exists in version 4.1.3

To me it seems that the following modifications fixes the problem, but a core developer should have a look on it to decide wether it represents the philosophy of sys_language_uid = -1 correctly and if there are any other cases to be considered:
