This was fallout from 9b980e269, aka bug #28412, where now we prompt for
buffers that have functions in the `write-contents-functions' hook. So
that's one more case to add to the list, and this interfered with some
package behavior, and this seemed like the simplest solution.

See the bug report -- if there's a better way of handling, this, that
would be great.
