Template:Subpages
From iGeek
This does the same thing as PrefixIndex -- but by being a template, lets it be an abstraction layer -- so that I could inject a 3rd party Subpage extension with different formatting at some point in the future, if needed.
{{Special:PrefixIndex/{{{1|{{FULLPAGENAME}}}}}/
|stripprefix={{{stripprefix|1}}}
|hideredirects={{{hideredirects|1}}}
}}
