Back out previous delta to fix fsck on filesystems without an fstab entry,

where we want to take the disklabel filesystem type of "4.2BSD" and use
fsck_4.2bsd on those filesystems.

Add a comment about why the code is there, now that we know:

         * XXX This is a kludge to make automatic filesystem type guessing
         * from the disklabel work for "4.2BSD" filesystems.  It does a
         * very limited subset of transliteration to a normalised form of
         * filesystem name, and we do not seem to enforce a filesystem
         * name character set.
