I'm afraid I don't "get" your problem statement.
As I understood it, you told that,
1) say, let the history of hello.txt includes 3 commits, and
2) you'd like to see three diff views -- one for each of
those commits, and
3) each such diff view should display the changes between
the indicated commit and its parent commit.
Is that correct?
If yes, then if a commit has a name (its sha-1 hash sum) <rev>,
then the name of its first (or sole) parent commit is <rev>^1,
and the way to get a difference between them is by passing these
two arguments to a difftool.
Just in case (to remove the possibility of a certain common
misunderstanding), a diff view is always generated between a pair
of commits ignoring any commits which might naturally form a chain
between those commits in that pair.
