We don't have a convention of an `-f' suffix in function names.
That form of name is extra cryptic.
Let's choose names that follow some existing pattern
rather than being inconsistent with old practice.

I suggest `defvar-internal', since it isn't meant for users to call.
Even `defvar-function' would be better than `defvar-f'.

For the doc string, it is better to say in a self-contained way what
the function does, rather than only make an analogy.

How about this:

   Define the variable VAR, with initial value INITVAL and doc string DOC.

Note that `defvar', being a special form, can distinguish between nil
as INITVAL and having only one argument.  However, a function cannot
do that: it will treat those two cases the same.
