Because tokens are "the atoms" of indentation and I think if we start
to go down this road, it will lead to disappointments in other cases
like

   x="<<$(cat food;
          cat litter)>>"

Yes.

Maybe you're right.  Maybe it's OK to keep $(...) a single token when it
doesn't spread over multiple lines.  It'll prevent `smie-auto-fill` from
inserting a new line inside of it, but other than that it might work
well enough.
