Finally had a chance to poke at this a bit more ...

In your post there, you said:

So very close.

zstyle ':completion::complete:git-diff*:argument-rest:tree-files'
command 'git ls-files -m'

One question is why ^Xh (list-tags) shows the "files" tag for that
context but not the "tree-files" tag.  If you invoke completion
immediately after "git diff " (instead of after "git diff HEAD ") then
the context is "changed-in-working-tree-files" and THAT gets shown
correctly by ^Xh.
