Pagination limit configuration change in core modules.

Alright I think I found it ! It's in admin system informations. Maybe the title ("Number of posts on front page" ) of its select is a little missleading.

system.admin.inc, line 1457 :

  $form['front_page']['default_nodes_main'] = array(
    '#type' => 'select', '#title' => t('Number of posts on front page'),
    '#default_value' => variable_get('default_nodes_main', 10),
    '#options' => drupal_map_assoc(array(1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 15, 20, 25, 30)),
    '#description' => t('The maximum number of posts displayed on overview pages such as the front page.')
  );

Any of you would agree to change t('Number of posts on front page') to something like t("Maximum number of posts per pages") ?
I am going to make a patch.

You're right it's about nodes, maybe they didn't realise the usefulness of this setting and how it can be related to other purpose than just "posts on front page" like suggested. That's why in my patch I proposed the string title "Maximum number of nodes per page" instead.

I'll try to explain this clearer, because it seems worse than I thought.

The issue is related to the actual default page limit, its administration's setting located in Site information (which is OK) is named "Number of posts on front page" which seems totally missleading, because what has been called "Number of posts on front page" is really the default pager elements limit set by the persistent variable 'default_nodes_main'.

Indeed, the persistent variable named 'default_nodes_main' is used to define the default pager's element per page limit for just any page element, not only front pages or nodes.

For exemple I am working on a module with a table generated with (theme_table) in which I insert rows composed of string and date types. Rows data is retrieved by a PagerDefault query :
->db_select("...")->extend('PagerDefault');
And the form has a pager control :
$form['pager'] = array('#theme' => 'pager');

Its page limit is not related to nodes, yet it is configured by the "Number of posts on front page" setting.

The administration field name should be changed to something like "Pager elements limit" with a description similar to "ie. the Number of posts on front page", to improve both users and developpers experience.
