Jan> Thanks a lot for the cooperation. I hope mutual cooperation isn't a surprise. Jan> Does that mean this will be in a released Emacs soon? In Emacs 21 (for an unknown value of `soon'). Your theme support (thanks) should be ported too when someone has the time. Jan> The problem with this is that the whole Jan> custom-set-*s interface seems fragile to me with regard to future Jan> extension. Jan> Do you think it would be a good idea to move this to keyword Jan> arguments? Then we could specify that unknown keyword arguments must Jan> be preserved but ignored. That sounds reasonable to me, at least. Jan> i.e. Jan> (custom-set-variables Jan> '(gnus-ignored-from-addresses "vroonhof＠.*math") Jan> '(gnus-decay-scores t nil :comment "This variable is important"!) Jan> Is it too late to do this now? We currently only have this in beta Jan> releases so we can still make the changes. For us now is a good time to make such a change.
