You will see that, but only if you did an update after you've last
committed the now merged file.

The same here: if you have updated after you last committed that file,
you will get the merge view with the correct revisions.

TSVN does not know which files are affected in an update *before* the
actual update. But after the update has finished, it can't check what
revision the file was at in the working copy before the update to show
you the diff you would expect.
So the only workaround is to get the revision the folder you run the
update on has in the working copy before the update.
