Request #340 has been accepted by arcanis [1]: If you visit the project repo, you will see that this script is a fork of script which is on the link provided by you.
But I've remove this package and 'irssi-script-bitlbee-facebook-rename', because 'irssi-script-bitlbee-facebook-rename-git' is a correct name for this script. [1] https://aur.archlinux.org/account/arcanis/
