This is related to T234133 but the contrary: Say I want to process double and broken redirects except on some namespaces (e.g. NS_USER and NS_USER_TALK). Instead of specifying a long list (and growing) of namespaces, give Pywikibot a list of namespaces where you do not want the bot to edit.
Suggested in eswiki. Some users would prefer redirect-fixing bots not to edit on NS_USER/NS_USER_TALK and its subpages.
