Port missing pieces of i18n_node.module to D7

Looks great, you even added some test, thanks!

This is committed. There are a few minor issues with this page though that we can fix with next patches:

- Language neutral showing up?
- Language names for fields.

(changed issue status to active, instead of fixed, though patch is committed)

Fixed, thanks.

A small nit when reviewing this issue for examples of tests... I think that the middle test below was meant to make sure that the english autocomplete suggestion was found. Am I wrong?

+    // Check the autocomplete suggestions.
+    $this->drupalGet('i18n/node/autocomplete/page/es/' . substr($es_title, 0, 3));
+    $this->assertText($es_title);
+    $this->assertNoText($en_title);
+    $this->assertNoText($ptbr_title);
+
+    $this->drupalGet('i18n/node/autocomplete/page/es/' . substr($en_title, 0, 3));
+    $this->assertNoText($es_title);
+    $this->assertNoText($en_title);
+    $this->assertNoText($ptbr_title);
+
+    $this->drupalGet('i18n/node/autocomplete/page/pt-br/' . substr($ptbr_title, 0, 3));
+    $this->assertNoText($es_title);
+    $this->assertNoText($en_title);
+    $this->assertText($ptbr_title);

OK... But then what is the purpose of the third test? It appears to be like the first of the three just using a different parameter.

Thanks for the explanation... I am learning more about testing all the time and am now including an in-line comment in my own code above what here was 1), 2) and 3). It helps me remember in plain text what condition was being tested for.

I am seeing you get all languages for autocomplete (enabled and disabled ones) which is not consistent with other options (extended language option for nodes) and also not consistent with the list above.

See screenshot. Chinese and Portuguese are disabled languages.

Committed, thanks.

It works great now!

Keeping our list clean.
