| The following code fails for me:
| 
|    line(1:10, 1:10)
|    clf
|    line(1:10, 1:10)
| 
| with the following error:
| 
| error: __go_line__: invalid parent
| error: evaluating assignment expression near line 52, column 5
| error: called from `__line__' in file `/home/sh/__line__.m'
| error: evaluating assignment expression near line 35, column 7
| error: called from `line' in file 
| `/home/sh/Programmer/share/octave/2.9.9+/m/plot/line.m'

I think the following patch should fix this problem.

Thanks,
