I remember encountering some system where this didn't work.
Unfortunately, I don't remember which one.  It has to do with this
part of the 'strings' spec:

  A printable string is any sequence of four (by default) or more
  printable characters terminated by a <newline> or NUL character.

You can't be certain that the test word will be followed by a zero.
