[Ecls-list] read and recursive-p

[Raymond Toy]

Here's a little test program:

(with-input-from-string (s "abcdef")
  (loop (read s nil 'eof t)))

With gcl, clisp, and cmucl, this loop is an infinite loop.

However, with ecl, this code produces an end-of-file error.

I'm not very sure about what exactly is supposed to happen when 
recursive-p is non-NIL, and error-p is NIL, but I think an error is not 
supposed to be produced.  (This causes some problems with f2cl and ecl, 
but I think f2cl is using setting recursive-p in some places it probably 
shouldn't.)
