Here's another enhancement that will help those people (like me) remember
to change the mode, owner, and group of the new file.  This enhancement
follows the previous patch (posted to this group) and will change the
modes of the new binary to match the old binary.  Then the mv(1) command
can be used and will keep the modes the same.

NOTE:  Found another file that needs to be converted for those who have
DOS-73 boards.   /usr/bin/DOS-73.

I'm sure there are more, I'll do an exhaustive search and post my results.
