Subject: [PATCH] observer: Coerce scalar values in keys to sets

Unfortunately, strings are iterable in python, so without this a call with a
single string, or a construct of "('foo')" would result in creating keys for
each letter of the string 'foo'. "('foo',)" works, because , creates the tuple,
not the parens...
