function i18n_sync_node_translation in Internationalization 7

Synchronizes fields for node translation.

There's some specific handling for known fields like:

• files, for file attachments.
• iid (CCK node attachments, translations for them will be handled too).

All the rest of the fields will be just copied over. The 'revision' field will have the special effect of creating a revision too for the translation.

Parameters

$node: Source node being edited.

$translations: Node translations to synchronize, just needs nid property.

$fields: List of fields to synchronize.

$op: Node operation (insert|update).
