Frankly, it should be obvious: you are recursively invoking the same
operation that is being processed by the calling function.

I added a note about this to the doc string of define-coding-system.
However, I really doubt that this will do any tangible good, since we
don't document how to define a coding-system.  The ELisp manual says
just this:

     How to define a coding system is an arcane matter, and is not
  documented here.

Any reasons not to close this bug report, now that all of its aspects
have been addressed?

Thanks.
