That's what I assumed, but is it documented?  (I briefly looked but
didn't see anything relevant.)  And although it's probably not too
common to enable whitespace-mode in a non-editable Gnus buffer, it is a
gotcha if you happen to do so.  It would be user-friendly to prevent
that, but maybe the effort isn't worth it.
