Help for Content Type Settings is confusing

Issue Summary

The help entry on the Content Type Settings admin page (admin/content/page_title/types)
displays this:

By default, a 'Page Title' field will be displayed (just below the 'Title' field) on every content type's creation form. You may hide this field for each content type below.

Below is a list of node types. The node types checkboxes are by default unchecked
The help description above the list of node types says:

Display a "Page title" field for these content types.

implying that checking a node type will result in the display of a textfield to
edit the page_title for a node.

The actual behaviour is that checking a node type checkbox will turn on the
display of a page_title textfield in node edit. So the help entry at the top
of the page presents the opposite information.

Also a secondary thing but perhaps the admin user should always be able to
edit the page_title in a node edit form...
