[issue5686] Float formatting with no type code produces incorrect output for exponential notation

[Eric Smith]

New submission from Eric Smith <eric at trueblade.com>:

If no format specifier is supplied to a float, it's supposed to work
like 'g', but with at least one digit after the decimal. This works for
non-exponential notation:

>>> format(1., '')
'1.0'
>>> format(1., 'g')
'1'

But for exponential notation, it does not:
>>> format(1e200, '')
'1e+200'
>>> 
>>> format(1e200, 'g')
'1e+200'
