It seems the required changes would fit in nicely in output_float():

We can treat FMT_G like FMT_E. After the rounding step, i.e. when the final
value of the variable e in output_float() is known (at the label 'skip'), if e
is within limits for F editing, revert the formatting to F and add the blanks
at the end.
