Oh, I missed the :set function for defcustom.

I'm probably just being dense, but the customization interface in Emacs is a 
bit confusing for me, so I've always just put «setq»s in my init file. 
Requiring use of the customization interface for users who are accustomed to 
directly editing init seems a bit Windows-esque, but at least if the docstring 
says it's required, then it won't be misleading.
