It is trivial if you realize that X is the change between the HEAD and the
index, and Y is the change between the index and the working tree. Most
importantly, no direct comparison between the HEAD and the working tree
gets in the picture.

    $ mv COPYING RENAMING
    $ ln -s RENAMING COPYING
    $ git add COPYING
    $ mv RENAMING COPYING
    $ git status -suno
    TT COPYING

I dunno.

An obvious alternative is to add T next to all occurrences of M in the
table where we say "M is possible", but unless it is accompanied by an
explanation "T is just a special case of M", I suspect the resulting
description would be harder to understand than currently is, and as long
as the reader understands "T is just a special case of M", then there
isn't much point adding T everywhere M appears in the table anyway, so...
