r.line

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'.
