Documentation should reference the new syntax needed to prepopulate a node body

The following prepopulate URI (from the old Julian Bond bookmarklet) worked fine with Drupal 4.x, but with the new DRUPAL-5 cvs prepopulate.module, the title of the new post is filled out correctly, but the body area is left completely blank:

/node/add/blog?edit[title]=this%20is%20the%20title&edit[body]=body%20goes%20here

this is the example given in the prepopulate.module docs. The edit page loads as expected, the title is set which appears to confirm permissions to post, but the body is empty.

in the package for prepopulate.info,v 1.1 (2007/01/27 16:07:05 eafarris) the docs do say we need to grant permissions:

3. For each content type that you want to allow prepopulating, set the
prepopulate checkbox in admin/settings/content-types

but I see no such checkbox at that path in 5.x, and no settings appear for either the prepopulate.module, or for permissions or the configuration for blogs or nodes.

the prepopulate module is really very small; 'workflow' is mentioned in the code, so is it possible the docs have failed to state a dependency?
