2. 6.4 revisioning_api.inc \_revisioning_delete_revision()
3. 6.3 revisioning_api.inc \_revisioning_delete_revision()

Delete selected revision of node, provided it's not current.

This is same as node_revision_delete_confirm_submit() in node_pages.inc, except it doesn't put any messages on the screen. This way it becomes reusable (eg. in actions).

@TODO: Insert check to prevent deletion of current revision of node.

Parameters

object $node: Target $node object (loaded with target revision) or nid of target node

int $vid: (optional) vid of revision to delete, if provided $node is not object.
