Evaluate the following code:
(list
(documentation-property 'aaa 'variable-documentation)
(progn
(defvar aaa ?\x9216)
(documentation-property 'aaa 'variable-documentation)))
For me it is (nil *trash*)
*trash* is a string from Lisp internals that varies from installation to
installation but seems not to depend on the arguments of `defvar'.
Seen in both latest xemacs-21.4 and xemacs-21.5
