I hope you are all well, and my apologies for the long delay on this.

I went ahead and applied your updated patch to 'emacs-27' with a small
wording tweak and merged that into 'master' as well.  I'll also get to
your other patches over the next few days.

Thanks again,

[Message part 3 (message/rfc822, inline)]

From: Olivier Certner <ocert.dev <at> free.fr>

Applies to 26.3, but also all more recent versions as well.

Bug trigger:
1. Load ERC (e.g., open some IRC connection).
2. Launch ibuffer (e.g., type "M-x ibuffer").
3. Switch formats three times (e.g., type "`" three times).
4. You get this error: (wrong-type-argument listp erc-notice-face) and
the buffer is only partly filled, and then cannot be updated.

Root cause:
erc-ibuffer assumes (in (define-ibuffer-column erc-modified ...) form)
that erc-modified-channels-alist is an alist whose values are proper
lists, whereas they are dotted lists.

Patch:
To be attached shortly after bug creation.
