SubPage/LongPrefixBeforeEachPage

For instance, many pages on the C2 wiki have titles like ExtremeProgrammingSomeSubTitle?. With subpages, most references to these pages could be of the form /SomeSubTitle?, with occasional use of ExtremeProgramming/SomeSubTitle?.

This page is a good example of a short definition subpage. It probably wouldn't rate a full top-level page.
