Preliminary patch

Here is just a experimental patch. Yes we could do some things in output float.
 I will think a bit on that.  The patch also has adjustments to default widths.
The default widths require quite a few test suite adjustments, which I have in
my tree and will post later to pr48488.

I believe the intent of this code block in write_float was to reduce the number
of digits converted in the later snprintf calls as a simple optimization.
