`fill-nobreak-predicate' was set locally, so it would be removed when
the mode for the buffer was changed. Previously, `unload-feature'
failed to do so unless the mode package's FEATURE-unload-function,
assuming one existed, did by itself. Since revno:104702
`unload-feature' does so automatically, so the above case should work
(i.e, unloading sgml-mode will change the buffer's major mode to
text-mode).
That said, I'll add that variable and some of the others you mentioned
to `unload-feature-special-hooks' because it's better to be safe than
sorry. But, what would be nice is some way to identify hook variables
in a generic way, instead of special-casing still more of them. :-(

OK.

I cannot find that one in the Emacs sources.
