Forked from https://en.wikipedia.org/wiki/User:Ajbura/anrfc-lister.js. A big thanks to the original author, Ajbura.

HOW TO USE:
- go to a talk page
- click More -> ANRFC Lister
- there will now be "List on ANRFC" links next to each section. click one
- fill out the form
- press "Submit"
- the script will add a listing to WP:ANRFC for you :)

SKINS IT WORKS IN:
- vector
- vector-2022
- timeless
- monobook
- modern

SKINS IT DOESNT WORK IN:
- minerva

CHANGES BY NOVEM LINGUAE:
- Linted code. Added comments. Refactored.
- Works on testwiki now (gives a local WP:ANRFC link instead of an enwiki WP:ANRFC link).
- Fixed bug where the script was always in an endless loop
- Fixed bug where the RFC would always get placed at the bottom of the page, not in its proper section
- Fixed bug where section heading (the # part of the wikilink) was not getting added to WP:ANRFC
- Fixed bug where More -> ANRFC Lister link was the wrong size and did not match the style of the skin
- Fixed bug where no signature or a signature too far down caused it to hang forever
- Added a "Cancel" button to the form
- No longer displays on special pages, diffs, editing a page, etc.
- Clicking "Would you like to see it?" now takes you to exact section, instead of top of page.
- Fixed duplicate RFC listing detection.
- Titles shouldn't have underscores
- Fixed bug where the script would always give "signature not found" error if you had MediaWiki:Gadget-CommentsInLocalTime.js gadget installed

NOVEM LINGUAE TODO:
- test unicode titles
- test titles with weird punctuation in section names, e.g. ending in ?
- get it working in Minerva
