Good catch, thanks! I've changed all of the `return` statements in this patch to `break` for consistency, though for the other ones it doesn't really matter. For patch #3 I also changed the `return` to a `break`, but for patches #4 and #5 the return was better so I left those. v3 posted now with this fix. -Doug
