Two fixes to what I suggested:

(1) (Aesthetic) Get rid of the OIFS line; it's never used
(2) (Bugfix) Near the start of xdvi, there's a line which reads:

    NAMEOPT='-name xdvi';;

    This must be changed to read:

    NAMEOPT='-name
xdvi';;

    as otherwise, xdvi.bin sees the single argument "-name xdvi",
    which it doesn't understand.
