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.
