[TYPO3-core] RFC: #15958: Bug: sections in flexforms require user to have access to default language

[Andreas Kiessling]

Reminder

Quoting myself:
The guide (doc_l10nguide) suggests "Use: [All] language" for all three 
types, but for
"Disabled" also "Alternatively you can of course localize the record
with the core supported localization like any other record."

So please agree with me, that sections should be modifiable for an
editor if language > 0, because they have nothing to do with the
sections from the default record.
$GLOBALS['BE_USER']->checkLanguageAccess($row[$languageField]); from v2
can be skipped in that case, otherwise check for access to language 0 is 
of course needed.

Regards,
Andreas
