 I should have made my earlier reply more explicit. It doesn't seem to be
 a failure.
 
 The part of the hexdump(1) manpage quoted previously:
 
 o A byte count or field precision is required for each ``s'' con-
 version character (unlike the fprintf(3) default which prints
 the entire string if the precision is unspecified).
 
 And as observed hexdump does accept the required value when passed a
 "field precision" - the numeric value immediately after the period in
 "%.4s" (NB not a "field width" - as described in fprintf(3) and slightly
 more clearly in printf(3)).
