Add support for robots meta tag - Using private function of Meta tags

Subscribing.

I'll take a look at this module and see if I can offer a patch.

Patch attached which shamelessly lifts code from the nodewords and nodewords_nodetype modules :)

A bit late, but committed and thanks.

The patch uses a private function of Meta tags, which is not necessary kept between an official version and the successive.

It's not the patch itself that's using the private but rather the module. Patch is fine.

Private function issue @ #483286: The code uses a private Meta tags function

The patch code calls _nodewords_check_content() in the following code lines:

+        if ( ( $robots = variable_get('nodewords_nodetype_robots_'. $node->type, '') ) !== '' ) {
+          $tags['robots'] = _nodewords_check_content(token_replace($robots, 'node', $node));
+        }

I know, but it just copies what I do on other lines of the code. I am accepting the patch because although the private function is there, it's as well on the original module. It makes no sense continuing the discussion here while we are talking about it in the other issue. And besides, the patch was already committed and released on the new version of the module.
