I do not think that adds much value.  When A or B is a
non-commit, you know that A...B notation does not apply, and
because it is probably a rare situation you would want to make
it even more clearer to the reader by using a different
notation.  Like

    echo "* $name have changed from submodule $sha1_src to blob $sha1_dst!!".

perhaps in red bold letter in larger font ;-)
