Cannot uninstall comment when node is disabled.

In hook_uninstall() the module cleans up variables like this:

  $node_types = array_keys(node_type_get_types());
  foreach ($node_types as $node_type) {
    field_attach_delete_bundle('comment', 'comment_node_' . $node_type);
    variable_del('comment_' . $node_type);
    variable_del('comment_anonymous_' . $node_type);
    variable_del('comment_controls_' . $node_type);
    variable_del('comment_default_mode_' . $node_type);
    variable_del('comment_default_order_' . $node_type);
    variable_del('comment_default_per_page_' . $node_type);
    variable_del('comment_form_location_' . $node_type);
    variable_del('comment_preview_' . $node_type);
    variable_del('comment_subject_field_' . $node_type);
  }

A lot of comment modules variables are postfixed with node types, so what do we do? Let node module clean them up? Leave them? Delete based on the first part of the variable name?

Come to think of it - if the variables are going in CMI-config files at some point, then this issue more or less solves it self.

Here's a test.

As of the latest patch in #731724: Convert comment settings into a field to make them work with CMI and non-node entities, this would be obsolete. Still worth fixing in case that doesn't land.

10 months later this is still a problem and it is still blocked on #731724: Convert comment settings into a field to make them work with CMI and non-node entities

Would love your help over there (see to-do list in issue summary).
We've been re-rolling it since November.

Comment is now a field
