has the form `(when CONDITION . SPEC)', the specification SPEC applies
only when CONDITION yields a non-nil value when evaluated. During the
evaluation, `object' is bound to the string or buffer having the

bound to the position within `object' and the buffer position where
the display property was found, respectively. Both positions can be
different when object is a string.

`(:when t SPEC)'.
`(when t . SPEC)'.
