That's what the code currently already does.  But: See what I wrote
about the purpose of the patch: our saving code needs to modify how
elements in the hash table are printed.  The Lisp printer doesn't allow
that per se.  My suggested patch substitutes a very inefficient hack
with a more efficient hack.  The current code uses printing + re-reading
AFAIR - and that on nested hash tables.

I thought long about removing the need for this hack altogehter, but
this is very complicated, if not impossible (yes, you would need to
change the printer).

Michael.
