So Gnus can differentiate between the default value and the user's
explicit nil setting.  Gnus automatically adds its function only if
the user hasn't provided a setting.

I think it's defvar because someone thought defcustom couldn't handle
a list of functions, or the '(ignore) default.  I have next to no
knowledge of customize, so I don't know if this is true.

It's inserted automatically only if the user didn't supply one
manually.  It can be used manually just like Followup-To, to direct
the thread toward a subset of the lists, etc.
