git{,-blame}.el: remove old bitrotting Emacs code The git-blame.el mode has been superseded by Emacs's own vc-annotate (invoked by C-x v g). Users of the git.el mode are now much better off using either Magit or the Git backend for Emacs's own VC mode. These modes were added over 10 years ago when Emacs's own Git support was much less mature, and there weren't other mature modes in the wild or shipped with Emacs itself. These days these modes have few if any users, and users of git aren't well served by us shipping these (some OS's install them alongside git by default, which is confusing and leads users astray). So let's remove these per Alexandre Julliard's message to the ML[1]. If someone still wants these for some reason they're better served by hosting these elsewhere (e.g. on ELPA), instead of us distributing them with git. However, since downstream packagers such as Debian are packaging this as git-el it's less disruptive to still carry these files as Elisp code that'll error out with a message suggesting alternatives, rather than drop the files entirely[2]. Then rather than receive a cryptic load error when they upgrade existing users will get an error directing them to the README file, or to just stop requiring these modes. I think it makes sense to link to GitHub's hosting of contrib/emacs/README (which'll be updated by the time users see this) so they don't have to hunt down the packaged README on their local system. 1.
