multidimensional

That's consistent with __cpp_multidimensional_subscript.

I've rebased the PR onto the current main. No new problems have been found in the commits in between.

Do you mean only one commit per word, or just that a commit shouldn't fix multiple words? The former will result in long commit messages, if I need to enumerate all the subclauses. The latter will result in shorter messages, but you still won't be able to review all the changes to one word at a time.

For the former, if there are more than 2-3 subclauses, you can use [std] if it spans multiple Clauses, or refer to parent subclauses rather than the specific subclauses. For example, 7cc17d9, for "subdirectories", can just be [filesystems].

Thanks, much better. Please add "hyphenation of" after "inconsistent" in each commit message.

Thank you for the very tidy commits!
