Thanks for the review.

That's correct, although even if that were the case that wouldn't be an
issue with this migration, as we'd have been using "the_index" before,
just indirectly through a macro.

That wasn't the case here, but I do I have another similar migration for
migrating "the_repository" wrappers.

In those cases there's surely instances where e.g. we really should be
using a "r" argument instead, but I've opted to leave that question out,
as it would make the coccinelle rules involved & diffs much harder to
deal with.

And because in the end the result is the same if viewed with "cc -E",
i.e. these are just the macro shims we've been meaning to stop using for
a while.
