I found out the bug of 'r.line' has not been fixed in the
current release. This bug can be removed as following.
-----------------------------------------------------
1. change directory to:
$GISBASE/src.aplha/raster/r.line/cmd
2. edit the io.c file by:
a) move to the function of write_ln (begin,end,n);
b) add the following line after the variables declaration:
Vect_reset_line (Points);
make sure this command is in front of the first appearance
of Vect_append_point (Points, x, y);
3. change direcotry to r.line:
cd ..
4) run 'gmake4.0' to recomplie 'r.line'.
