Maphash

[Scott E. Fahlman <Fahlman@CMU-CS-C>]

One of my hackers has just noticed that we still map over the elements
of a hashtable with MAPHASH, while we have changed most similar forms to
DO-mumble, as in DO-SYMBOLS, etc.  Since MAPHASH returns NIL, there is
no elegant way to turn the contents of a hashtable into a list.  What
would people think of flushing MAPHASH and replacing it with
DO-HASH ?
