Thanks for putting everything together :-) looks like a 'letter to Santa' or to the three Wise Men, which would be just in time in places like Spain ;-)

> 1. Whether to load `custom-file' automatically after the init file is an open question.
Agree, but it would be a nice place, right? You have setup all the code you use in your emacs, you are sure that all variables have been defined and then you initialize them with the values you want/have customized

> 2. That should never be done if it's already been loaded...
100%, see my patch as a simple way of accomplishing that

> 3. ...(Obviously this can only be the case when it's not the same file as the init file.) 
Hmm, right, I was missing that part :-)

> #3 is a no-op if the `custom-file' is empty...
Right, I was assuming that, but it's better if we write this out

> 4. ... Why?  Just as you might want to explicitly control where/when, and how many times,...
That sounds fair

> 5. `emacs -q' and `emacs -Q' should not load the `custom-file'. 
So we put in in the same (progn) that loads the init file

> In addition, we should add a new switch that suppresses (only) loading of the `custom-file'
Don't get that one

> 6. `custom-file' should have a default value/location.

I'd favour that

Good analysis...

Thx, /PA

Isn't it already separate if you want to?  IOW, can't you already change
the custom file?

I don't think it would be easier for debugging.
