Special page with spaces cannot find by mwsuggest when have the space inside the search term.
For example. Search for "Spezial:Vorlagen expandieren" (Special:ExpandTemplates) on de.wp. After typing "Spezial:Vorlagen e" the scrolldown box is missing.
The problem is, that PrefixIndex::specialSearch get the title without underscores, but the alias is stored with underscore.
Thanks.
Am not sure, which is the best component, so use "General" for now.
