Remove "delete" button from node forms

Since this module provides links to delete a node, "delete" button in node form is no longer necessary. From end user point of view it is also confusing to have 3 submit buttons for a form.

I propose to remove "delete" button from all node forms.
This can be accomplished by the following code:

/*
* Implementation of hook_form_alter().
* Removes "delete" button from node form.
/
function admin_links_form_alter(&$form, &$form_state, $form_id) {
  if ( substr($form_id, -strlen('node_form')) == 'node_form' ) {
    unset($form['buttons']['delete']);
  }
}
