json.el can use all the help it can get ;)

In any case, I was putzing around and turning on lexical-binding all
over the place and found that many files byte-compile happily with
lexical-binding enabled, or with minimal changes.  Seems like a lot of

head -n1 -q lisp/*.el|grep -v 'lexical-binding'
