[sets *read-default-float-format*, saves image]

As of version 1.5, I/O control variables that are bound by with-standard-io-syntax are thread local.  This includes *read-default-float-format*.

It's possible to set the default initial binding for thread-local special variables with a form like this:
(ccl::def-standard-initial-binding *read-default-float-format* 'double-float)

We probably need to have a documented and exported way to do this...
