I see nothing in any of the doc (doc string, Emacs manual, Elisp manual) where 
we talk about `C-x RET c' being a "prefix argument". And we should not, IMO. It 
has nothing to do with a prefix argument, except that it reads a key sequence 
and handles reading a prefix argument in doing that. It certainly is not a 
prefix argument for the command it is bound to, nor does it provide a prefix 
arg for the command it is bound to.

Even `C-u' (`universal-argument') is not a prefix argument. It is a command 
that begins reading a prefix argument and that, possibly together with other 
commands (such as `digit-argument') provides that prefix argument to a followup 
command.
