Summary: Print identical floats consistently

Initial Comment:
Hello again and thank you,

This is a rewrite of now-closed bug #1534769.

As you know, 

>>> print .1
>>> print (.1,)

give different results because the __str__ call from
print becomes a __repr__ call on the tuple, and it
stays a __repr__ beneath that point in any recursion. 
>From the previous discussion, we need behavior like
this so that strings are quoted inside tuples.

I suggest that print use a third builtin that is
neither __str__ nor __repr__.  The name isn't
important, but suppose we call it __strep__ in this
feature request.  __strep__ would pass __strep__ down
in the recursion, printing floats with __str__ and
everything else with __repr__.

This would then

>>> print .1                and
>>> print (.1,)

with the same precision.

Marc
