lua(abi) should be required automatically when packages install files to a specific location.

Thanks. Removed that line.

Not sure we need this paragraph. Other language specific guidelines don't have this either. But having it probably doesn't hurt ...

This doesn't render correctly. Code blocks that are to be included verbatim need to be surrounded by .... (four dots).

Alternatively, if you want syntax highlighting, the format to use is

[source,<language>]
----
<contents>
----

This is missing the second plus character, should be `+lua-modulename+.

We don't keep historical records in the Packaging Guidelines. There's no need to say "only supported on Fedora >= X" if all current branches already support it.

Same here, needs to be four dots, not three.

And again, four dots, not three.

EPEL specific guidelines are maintained separately:
https://docs.fedoraproject.org/en-US/epel/epel-packaging/

But I'm not sure it's worth documenting a small thing like that separately, so it's probably fine to keep it here.

I left some comments, mostly wrt/ AsciiDoc syntax / formatting problems. Sorry that this is taking so long ...

Fixed the AsciiDoc syntax problems, rebased on top of master: https://pagure.io/packaging-committee/pull-request/1298

Note that decathorpe made the asciidoc fixes, and opened a new PR (which is getting merged): https://pagure.io/packaging-committee/pull-request/1298
