local variables if they are used more then twice.

"more than once"? "twice or more"?

Well, its "more than twice", as you did:

-               if (change_color)
+               if (wops->change_color)
                        color = obj__set_color(obj, HE_COLORSET_ADDR);
                obj__printf(obj, bf);
-               if (change_color)
+               if (wops->change_color)
                        obj__set_color(obj, color);

Ok, I wouldn't touch this, i.e. would leave all as local variables that
way the patch would be smaller :-)

So its just 'then once' to 'than once' the fixup.

Oops, will fix in v2.
