In order to minimize the differences in the footer.

Asciidoc automatically generates a date with format '%Y-%m-%d', while
asciidoctor '%F'.

I personally prefer the latter, so only modify it for diff purposes.

Fixes tons of these:

-Git omitted                       01/01/1970                        GIT-ADD(1)
+Git omitted                       1970-01-01                        GIT-ADD(1)

Is that really the format Asciidoc uses? Not that it matters much for
the purposes of this patch.

I agree completely.

Nice.

If you introduce a separate Makefile flag and incorporate Peff's patch
to doc-diff "asciidoctor" and "asciidoctor-direct", you'd need to
duplicate this a bit, or maybe just emit the ASCIIDOC_EXTRA outside of
the whole if chain.

You could follow up with the patch below. If you'd rather keep it out of
your series to avoid it ballooning, fine. I can repost it later, once
the dust has settled. Don't let it hold up your work.

Subject: [PATCH] doc-diff: drop --cut-footer switch

Now that our doc-diff convinces Asciidoctor to insert the exact same
formatted dummy date as AsciiDoc, we can drop the --cut-footer switch.
It has been useful to ignore this difference between the two tools, but
it's effectively a no-op now. Similar to when we repurposed this from
--cut-header-footer in 83b0b8953e ("doc-diff: replace
--cut-header-footer with --cut-footer", 2019-09-16), just drop it
without worrying about any kind of backwards compatibility or user-base.

Indeed.

I'll include it. Seems to fit the context.

Cheers.
