It's a shame one can't simply replace the [footer-text] template which

It turns out asciidoc 8.6.9-3 and later will habe a knob to turn:

https://github.com/asciidoc/asciidoc/pull/9

I'll try and get my hands on it to see whether we can simply use that.
I'm wondering though which is more useful - the version of the tree the
doc is processed from, or the version of the last commit changing the
corresponding doc source file. The first one changes even when the doc
source is unchanged (but is stable between reruns, of course).

I have 8.6.9-3 installed (it is part of Debian testing/unstable now),
and confirmed that:

diff --git a/Documentation/asciidoc.conf b/Documentation/asciidoc.conf
index 2c16c53..10c777e 100644
--- a/Documentation/asciidoc.conf
+++ b/Documentation/asciidoc.conf

drops the "last-updated" footer.

But note that this only affects the generated HTML. The manpages still
get the date in their footer. But this isn't an asciidoc-ism at all;
it's added by docbook when converting the xml to roff. I'm sure there is
a way to tweak that, too, but looking at docbook gives me nightmares.
