Author: mmetz

New Revision: 42296

Modified:
   grass/trunk/vector/v.info/level1.c
   grass/trunk/vector/v.info/main.c
Log:
clean up the mess: don't call Vect_get_num_primitives when map is not yet opened; don't override topo_flag for level 1 because there will be some info; don't open map twice; don't close map, then try to read map
