Details:

When assert compares two structs that differ it is difficult to determine to
which field the differences belong.  Example script tst_assert.m


x = struct ("a", 1, "b", 2, "c", 3);
y = struct ("a", 1, "b", 3, "c", 4);
assert (x,y)


And when it is run


octave:1> tst_assert
error: ASSERT errors for:  assert (cond {i},expected {i},tol)

  Location  |  Observed  |  Expected  |  Reason
     ()           2            3         Abs err 1 exceeds tol 0 by 1

ASSERT errors for:  assert (cond {i},expected {i},tol)

  Location  |  Observed  |  Expected  |  Reason
     ()           3            4         Abs err 1 exceeds tol 0 by 1


It would be nice if assert could report something about where the difference
lies such as


error: ASSERT errors for:  assert (y.b (observed), x.b (expected), tol)


or something similar.
