A @method annotation is only necessary when the docblock is not
directly followed by a function declaration (in which case JSDuck
assumes it documents a property), e.g. when defining an abstract
function or referencing a function from another library.
I verified that JSDuck generates exactly the same output before and
after this change (docs/data-<hash>.js files are identical).

Previously we passed either data.visualeditoredit.edit or data.error,
which was mostly okay since they are mutually exclusive, but it could
still theoretically conflict if both objects had identical properties
(and receiving different things could make debugging errors harder).
