Just like you did in 04/21, write "break" to avoid mistakes made in
the future, i.e.
default:
break; /* just use the configured value */

On a 32-bit arch with 2G int and more than 20 million paths in the
index, multiplying by max_split that can come close to 100 can
theoretically cause integer overflow, but in practice it probably
does not matter. Or does it?
