Vaclav,

   Following the link on that page to

<https://grass.osgeo.org/grass70/manuals/vectorascii.html>

provides details on each portion of the input file. I modified my input file
by adding a centroid (whose coordinates are approximately in the center):

ORGANIZATION:	Applied Ecosystem Services, Inc.
DIGIT DATE: 	2016-09-08
DIGIT NAME:	-
MAP NAME:	projbnd
MAP DATE:	2016
MAP SCALE:	-
OTHER INFO:	-
ZONE:		0
VERTI:
B 4
   -123.102155 45.215480
   -123.098186 45.215480
   -123.098186 45.211372
   -123.102155 45.211372
C 1 1
   -123.100170 45.213426

and grass is still not satisfied:
