So with the call to clean-up-path function and without the call to
strbuf_release(), mkpathdup() function becomes :

char *mkpathdup(const char *fmt, ...)
{
	struct strbuf sb =3D STRBUF_INIT;
	va_list args;

	va_start(args, fmt);
	strbuf_vaddf(&sb, fmt, args);
	va_end(args);

	return cleanup_path(strbuf_detach(&sb, NULL));
}
