This is entirely correct and is as it should be. I would further emphasize
that find() and match() only work at the top level.

Since match() always looks for slices, an atom as the first parameter is and
should be an error.  An empty sequence as the first parameter is also an
error--a return of 0 is preferable, as it would eliminate some special case
checking from code using match().
