Now deprecations can be read from interface files. To avoid a
lookahead of 2, the syntax for interface files has been liberated
slightly: They can end in as many freely mixed rule pragmas or
deprecation pragmas as you like.

Note: Parsing the deprecation pragma uses the same Lazy Technology (tm)
as the one for rules. Don't know if this makes sense, but it is
convenient here.
