Just a shot from the hip: In a shell, I believe the following
idea basically solves the problem:

  grep -E -n "\.TH|\.TS|\.TE" groff-tbl.troff | head -1

This would return 

  3:.TS H

from the table file that demonstrated the problem. Since it is
a ".TS" macro, the document is not a -man document. In other
words, one can just check if the first macro returned is a
".TH" macro and then it is a -man document, otherwise not. If
you could apply the finishing touches and convert to perl,
wouldn't that be a good solution?
