Though it doesn't show in the quoted message above (stupid mailer) in
the original message it looked like the string was padded with blanks.
Is that correct?  What does

   clear y
   y('adbc') = '1234';
   abs (y)

show?  Does it fill with blanks (ASCII 32)?  Octave fills with 0 and
then doesn't display the NUL character.
