Here is a snipped version of the code in question:
 vector/v.in.ascii/a2b.c

 for( i=0; i<n_coors; i++) {
    G_getl2()
    ...
    if ( sscanf(buff, "%lf%lf%lf", x, y, z) < 2 ) {
        G_warning("Error reading ascii file")
        return 0;
    }
    ...
 }



only the first three numbers on a line are scanned. The rest of the line
(if any) is undefined in meaning and, as currently coded, will be ignored.
