Or even
struct strbuf root = ((state*)opt->value)->root;
and then keep the next lines as is?

Eventually we want to have some sort of `init_apply_state` function or
a define which has all the values, I guess?
Compare for example to sliding_window.h, where
we have
struct sliding_view {
...
struct strbuf buf;
};
#define SLIDING_VIEW_INIT(..., STRBUF_INIT }
