Not quite, as that wouldn't handle the case where the configuration
isn't set. So we'd retain it as -1 and do the config lookup every single
time.

We could rewrite like this:

	if (o->source_paths_icase < 0 &&
	    repo_config_get_bool(o->repo, "core.ignorecase", &icase))
		o->source_paths_icase = 0;

But I'd argue that this is harder to read.
