[GRASS5] d.zoom patch?

[Martin Pokorny]

Hi,

I ran into a small problem with d.zoom in grass 5.7. There is an
uninitialized variable (smap) that causes a seg fault in main.c. I
just got rid of the variable and its references entirely---don't know
if that's the right thing to do, but it seems OK to me, and it has
fixed the problem. I've attached the (trivial) patch, if only so that
those in the know can see where the problem lies.
