You can write "See `name-of-first-variable' for a description of the
format for this option" in the next five variables.  Or even less
cool, write a macro that expand to a defcustom with the right doc
string.  

It would be cool with a function to create a option format
documentation string from a customize type, and to add a magic keyword
that is expanded that way to the 'documentation' function.
