Then how does one figure what "git clean -f -f" will do without actually
doing it?

Please notice that -f -f is special according to the manual:

  "Git will refuse to modify untracked nested git repositories
   (directories with a .git subdirectory) unless a second -f is given."

I looks like neither (0), nor (1) nor (2) gives us any useful behavior
in this case.

I figure the best solution is to rather make -n orthogonal to -f, that
will solve the puzzle, and that is what actually expected from a "dry
run" option: don't change any behavior, except print actions instead of
performing them.
