Separating Page lists

I made http://domain/short-doc/ a ‘private’ blog page,
so I can link it under ‘Articles’. But I really cannot accept WP shoving
“Private: ” at the front of the title.

How can I fix the title and still not have the page appear in the normal list of pages?

I really don’t want to go outside WP and construct the same appearance, with top and side-bars, in HTML.

Or what else would work to separate Linked-articles from Pages?
