No longer displays pages from a title. In some cases it will display a list of index pages.
For example, http://en.wiktionary.org/w/index.php?title=Special:AllPages&from=Hillsbo... a list of index pages from Hilma, instead of pages titles from Hilma.
http://en.wiktionary.org/wiki/Special:AllPages/Hiffe displays no pages at all, and clicking on "Go" switches to Prefix index.
Not useful. Can we put back the working version please?
