There is one remaining version check for 29:

nixpkgs/pkgs/applications/editors/emacs/make-emacs.nix

Line 173 in 07cfbb7

if lib.versionOlder finalAttrs.version "29" then

. Do you indent to leave that untouched?

[AndersonTorres]

I will not touch this check here.

This test controls the inclusion of an outdated patch, and it is covered by the commits below:

• d935537
• fea691e

I think it is better to split them in another step.

Edit:

On the other hand, a new commit can be added in this PR. Let's see...
