# does; in [[todo/autoindex_should_use_add__95__autofile]] Joey
# thought the old behaviour was probably a bug.
#
# The effect of listing a page in {deleted} was to avoid re-creating
# it; we migrate these pages to {autofile} which has the same effect.
# However, {autofile} contains source filenames whereas {deleted}
# contains page names.
