The code "moved" from holidays.el to calender.el is 'similar'
but not identical.  

It involves taking 40 lines from a function in holidays.el and change
them into a form suitable for initializing a defcustom in calender.el.

I agree that the 'transformation' is repetitive/mechanical, and the
end-result is functionally equivalent to the original code.  Still,
the change involves more than just "moving" code.
