Well, I suppose what we could do, without causing too much trouble, is
making ":e foobar" a no-op for a file where 'buftype' is "nofile" and
"foobar" is already the current buffer. It would be unexpected that a
plugin relies on this edit command to make the buffer empty.
I'll make a patch that does it this way, let's see if someone complains.
