Hello Chen-Yu,



this commit is so nice that:

- My heart says that it's fine as it is, but

- My brain says that it makes a lot more sense if you push the cleanup

changes to reverse that logic before pushing this commit, as to reduce the

count of changed lines (hence, to reduce some noise)...



...so please, can you rebase this commit over the cleanups?



Thanks,

- Angelo
