I have had a lot of luck in cleaning up vi on our particular version of
UNIX (*) by taking out the /etc/termcap boolean "xn" on a vt100 type 
terminal. The article failed to mention if UNIX was running native on the
PC (SCO Corp. ?) or via Smartterm. Also, make sure that on vt100's that 
the terminal has "wraparound" mode set. Otherwise your source file turns
into a horror show.
