v4. Drop erc-buttons patch. Be smarter when looking for faces to skip.


Just a minor update. As noted, I've dropped the first patch

  0001-5.6-Allow-ERC-modules-to-extend-erc-nick-popup-alist.patch

which has been installed on HEAD as

  e560f9af8e8 Allow ERC modules to extend erc-nick-popup-alist
