It's hard for me to say what is TRT here. If we explicitly ignore 
backups, does that mean we should add compiled objects files, etc, that 
is, everything from grep-find-ignored-files?

But I have configured my backups to be saved inside ~/.emacs.d/ 
directory, like a lot of people recommend. Via backup-directory-alist.

If you don't do that, and you have them saved side-by-side inside Git 
repository, don't you usually add .gitignore rules for them then?

So that they don't get in the way of other operations, outside of Emacs.
