mediawiki marks links to redirect pages with "mw-redirect" class, and links to disambiguation pages as "mw-disambig".
this allows editors to quickly and easily identify this kind of links, and correct them where a link to actual article is more appropriate.
links to redirects are usually considered harmless, and occasionally even desired, while unintentional links to disambiguation pages are almost always harmful.
the problem is that harmful link to disambiguation can "hide" behind harmless link to redirect page (where the redirect itself links to disabbiguation page).
the request is to mark such links (i.e. link to redirect page that redirects to disambiguation page) with both mw-redirect and mw-disambig.
(was not sure what is the best project to hang this on - finally selected "parser".
please move to more appropriate one if you can).
