So this isn't about the patch series. Question still remains the same.

Thanks for digging the history.

Why extra blank line?
Let's dig a bit.
Ah. I guess I found the reason. It's due to `putchar('\n');` in
`show_ref_array_item() [1]`. It puts a new line after each ref item.

Do you want me to include a patch to get rid of this "extra blank
line" for trailers in "for-each-ref"?

I do not know the answer to the last question, because we haven't
learned the original reason why we decided to add the extra blank
line after the trailer output.  Even though I find it unnecessary,
the code that adds it must have been written with a good reason to
do so, and I do not want to see us remove the "\n" without knowing
that reason.

Thanks.
