Well why are we changing it to have a .el extension? None of the other config files have extensions.

I wouldn't bother symlinking, though. It might prevent their config from breaking but it also means they won't get any of the updates and they might not realize that, which'd be worse. If anyone wants to pull updates from acmdots they'll need to re-run the install script.

My only other concern with the rename would be merge conflicts, but a symlink won't help with that. Git is probably smart enough to apply any changes to the renamed file, though.
