I don’t regularly use git, for some reason I can’t apply the patch?

$ git apply Eli2.patch

error: patch failed: lisp/progmodes/vhdl-mode.el:8785

error: lisp/progmodes/vhdl-mode.el: patch does not apply

$ git apply --reject --whitespace=fix Eli2.patch

Rejected hunk #1.

I’ve tried both the emacs-28.1 branch as well as the master branch, am I missing something?

Anyway, when I edited the code manually it seems to work fine :)
