[O] Straight recursive fact prints in floating-point in org-babel but not in REPL

[Brian Beckman]

Org-babel seems to print SLIME / SBCL bignums as floating point, at least in
this gist (please see
https://gist.github.com/rebcabin/f73cecd3c9b7da6218e9).  I'd like to be able
to control whether bignums are printed out in full.  Any advice for me?
