the \Z'...' does mean "zero width" (really!), so the
total width of this line is only the width of the
text "four inch" (which is less than 4 in.).

This is triggered by the two text lines

  Any line exceeding 4i will be reported.  The .em (enddi) prevents
  groff from complaining about the final diversion being incomplete.

all others are less than 4 in. wide.
