Yes: it uses the t value for its `invisible' property, but doesn't add it to
the buffer's invisibility spec.  As long as the invisibility spec is not
changed by any other major or minor mode, it works, but in general
it's incorrect.

Also I'd advise the package author not to use the `intangible' property,
since it tends to break other packages when they bump into it.
