So in the name of honestly, that's slightly misleading.

"git" will happily thread the actual index file up-to-date testing.

And that's hidden in the above numbers (because I didn't use "-f" to
follow threads), and they are all successful (because git will go an
'lstat()' on every single entry in the index file, and the index file
obviously is all valid filenames).

So the numbers quoted are closer to the

        git ls-files -o --exclude-standard

command (which doesn't check the index state, it only checks "what
non-tracked files do I have that aren't the ones I explicitly
exclude").
