Because while 8mm drives can append at any FM, it has to be on the
BOT side of the FM.  So you have to do mt fsf 1, mt bsf 1, if I
remember correctly.  Remember that the new EOD is where you stop
writing, you can't just overwrite part of the data.

mt feom takes care of getting you on the correct side of the FM;
I'm not sure right now if we made the append at any filemark work in 3.2 or
3.3, or perhaps not till 4.0

Life would be so much easier if we could just look at the source code.
