    MoinMoin - DeletedPages Macro

    This macro shows a list of pages that have been deleted by
    ?action=delete but still exist silently on disc.
    You need to be superuser to call this macro.

    Syntax:
    
    [[DeletedPages]]

    DeletedPages partly based on _macro_TitleSearch from
    wikimarco.py by Jürgen Hermann

    Changes:

    Version 1.1 by Oliver Siemoneit
    * Macro supports multilang if translations for
      '[Unerase] ' and '[Purge completely] ' are provided elsewhere.
