I'm using vc-dir mode.
I used "O" to show the outgoing changes.
In the *vc-outgoing* buffer, I selected the entire buffer
(C-x h) and then typed "=" to make a diff.
I was expecting to see a diff showing the combined contents of all 3 of
my outgoing patches.
However, the generated diff is missing the oldest patch in the series.

The appended patch fixes this for me.
I'll put it on the Emacs 26 branch after a few days, unless there are
comments.

Makes sense to me, please feel free to commit.
I don't particularly like how the region end is interpreted in this
command, though. I'd be more comfortable with the semantics of "show the
contents of all these revisions combined", which means replacing the
condition with t. Something to think about, for some future version.
