Jim pointed out that "tune2fs -f -O ^has_journal" won't remove the
journal if the needs_recovery flag is set; the manpage seems to indicate
that it should. And if you've lost an external journal and can no longer
replay it, how should one proceed?
Change tune2fs so that two "-f" options will allow removal of a dirty
journal from a filesystem, even if the filesystem needs recovery.
e2fsck can then do its best to pick up the pieces.
