Could be worse, could be perl.  In any case, filtering the existing
output does seem better than adding every imaginable formatting option
to dig.

... I *could* maybe see adding a formatting option to produce an
easier-to-parse output header, though, such as:

        ; OPCODE=QUERY
        ; RCODE=NOERROR
        ; QRFLAG=1
        ; AAFLAG=0
        ; TCFLAG=0
        ; RDFLAG=1
        ; RAFLAG=1
        ; ADFLAG=0
        ; CDFLAG=0
        [... etc ...]
