Correct.

All of the above give still useful piece of information to the
readers. I do not think it is a good idea to assume familiarilty
with pathspec limiting to all readers---a new reader must start
somewhere and diff-tree may just be a random place s/he started at.
So I do not think it is a good idea to drop this example or the
section from the page.

I agree with the patch that this paragraph should go.

Interesting. This does not work (and I do not think it has ever
worked) for a tree object 5319e4, but it works as advertised for a
commit object.
The description section has this near the top
If there is only one <tree-ish> given, the commit is compared
with its parents (see --stdin below).
I think s/given,/& it must be a commit-ish and/ would be appropriate
there; please include such a fix in a reroll.
I agree with this patch that it is a good idea to drop this example;
it is more appropriate to use "git show" on the commit-ish in the
case of the given example anyway.
