The comment paging isn't always added: you need to make sure you don't have
comments in the supports parameter (obviously), but if you turn off too
many things, it seems to default to turning them back on, somewhere I
couldn't trace (I didn't try too hard).

This example plugin for custom post type "cpt"
http://pastebin.com/FCDwJr2i produces these rules:

    'cpts/?$' => 'index.php?post_type=cpt',
    'cpts/page/([0-9]{1,})/?$' =>
    'cpt/.+?/attachment/([^/]+)/?$' => 'index.php?attachment=$matches[1]',
    'cpt/.+?/attachment/([^/]+)/trackback/?$' =>
    'cpt/.+?/attachment/([^/]+)/feed/(feed|rdf|rss|rss2|atom)/?$' =>
    'cpt/.+?/attachment/([^/]+)/(feed|rdf|rss|rss2|atom)/?$' =>
    'cpt/.+?/attachment/([^/]+)/comment-page-([0-9]{1,})/?$' =>
    'cpt/(.+?)/trackback/?$' => 'index.php?cpt=$matches[1]&tb=1',
    'cpt/(.+?)/page/?([0-9]{1,})/?$' =>
    'cpt/(.+?)(/[0-9]+)?/?$' =>

The attachments ones just seem to be always added as does the trackback
one. So you may need to add code to strip those explicitly.
Or else some extra magic with the ep_mask setting in the rewrite param (I
ended up setting it to 0 at some point).
