Pages containing Iban links which contain a redundant wikilink.

This occurs if link target consists of a single wikilink, which should instead be entered in the conventional manner without link brackets. For example, {{l|en|[[foo]]}} is the same as {{l|en|foo}}, and {{l|en|[[foo|bar]]}} is the same as {{l|en|foo|bar}}.

This also occurs when link templates are nested inside each other unnecessarily: e.g. {{l|en|{{l|en|foo}}}}
