Expanded that to a few more SUBDIRS noticed on the way, without the
backslash after the last item of each list, and applied the result.

We have quite a few more REGRESS lists in contrib/. Would these be
worth changing for test_decoding or pg_stat_statements at least?

I have a few questions:

1. Regarding splitting long lists: Is there an established convention or
threshold (e.g., maximum number of items per line or maximum line length)
that we should follow when deciding whether to break a list across multiple
lines?

2. I noticed that btree_gin, btree_gist, and pgcrypto also have relatively
long REGRESS lists, should we also update them?

3. Does this formatting guideline also extend to the DATA variable (for
example in contrib Makefiles), or is it mainly intended for REGRESS lists?
