Indeed, eliminating print-circle from byte-compile-output-docform was
correct when I did it (at which point -defmumble did not call
byte-compile-output-docform any more), but later I re-added the call to
byte-compile-output-docform and forgot to re-add the corresponding
print-circle.  Thanks for helping me catch it, should be fixed now,
