   I've encountered that problem often enough over many years to   
   get a feel for it as when action doesn't match logic.   
   Vim has a ':list' option that will display non-printiables   
   and for block files just re-write the suspect line. Also   
   have ADUMP that prints text and displays any non-printable   
   as '^nn', where nn was the value of the non-printable.
