Subject: [PATCH] Change default value of message-make-forward-subject-function

* lisp/gnus/message.el (message-make-forward-subject-function): Change
default value to be a list so it's easier for users to add
functions. Change the type so the customize interface allows selecting
multiple provided functions instead of just one.
