Comment:
I added some words and some examples (including corner cases) to the
function `kernel` in `sage/misc/functional.py` and to the `kernel` method
in `sage/matrix/matrix_rational_dense.py`.
Since the examples of the `kernel` method for dense integer matrices and
for sparse matrices are clear enough, I believe that my patch suffices to
clearify the documentation of `kernel`.
