Now this is *weird* :-)

This time I edited body of the function, in ~/.emacs, using emacs,
removing pieces, adding pieces (I'm not good at LISP!), just
experimenting, and resulted in the original function definition.

Now the two-space indentation works :-)

So I'll experiment with doubly- and triply-nested conditionals and see
if it works.

Thanks, it seems to be working!
