Eric understands why the scope was increased between the two; he explained why it is not a good idea to increase the scope in the middle, and I tend to agree with his reasoning. The reason why the scope was increased does not matter.

Then don't. Make sure the lines _you_ change are indented and formatted correctly. Do not touch near-by (or far-away for that matter) lines that you do not have to touch only to change the formatting.

Yes.

I do not think 'diff --check' would. Save the patch you sent to a file, edit it so that these two lines Eric pointed out are not changed, and then apply it with "git apply --whitespace=nowarn". Then ask "git diff --check"---it should not complain about an existing whitespace glitch that you did not introduce.

Unless it is a "here is a patch to reindent and fix whitespaces" patch that does nothing else, it is an unwelcome noise that distracts reviewers from the real changes.

This is not wrong per se, but just a

Please do not indent the body of the log message by one space.

I thought that Eric already pointed out and explained why this change to PACK6 is wrong in the previous round?

I also thought that Eric already pointed out that the above is not a good idea because it forces readers to wonder if "actual[1-5]" need to exist together with "actual" at the same time in the previous round?
