Since this output is being parsed in a script it would probably be better to use git status --porcelain, as that output is guaranteed to be stable (whereas git status --short is not).

Would it be possible to have an option to not run the standard excludes? I would like to be able to have .gitignored local files that still get applied in my nix config. I don't care about other users/programs on the computer reading them, they just don't make sense to be in the upstream repo.

(Also see #12291 for an alternative approach.)

FYI the else { and } lines use tabs to indent, while the rest of the file uses spaces.
