[PATCH v2 0/1] config: add back code comment

This is a follow-up to the kh/maintenance-use-xdg-when-it-should [series] which was merged in 12ee4ed506 (Merge branch 'kh/maintenance-use-xdg-when-it-sho.., 2024-01-26).

I dropped a code comment while iterating on a refactor. It still makes as much sense in this context as before the refactor (it’s a _refactor_ in the sense of “don’t change code behavior”).

The code comment was moved to `config.c` in patch v1 3/4.[1] But review feedback said that this comment didn’t fit in this new place and that we shouldn’t `die()` in `git_global_config`. So in v2 3/4[2] I removed the comment in `git_global_config`. But I forgot to put the comment back to its original place, where it still makes as much sense as before my series.

See the cover letter on the first version for the diff when I squash this patch into c15129b699 (config: factor out global config file retrieval, 2024-01-18).

Sorry about the churn.

§ Changes in v2

Add an ack trailer.

This is the (tentative) final version. I read (interpreted) `SubmittingPatches` as saying that the final version should be sent, even though it’s just to add an additional trailer. I’m open for feedback on the submission process of course.

I’ve added it after my signoff since it seems preferred to maintain the chronology (although in this case either choice seems equally clear). Also it seemed more common in the recent Git log.
