Bug? interactive echo clobbering softspace of redirected stdout?

[Bengt Richter]

ISTM it's a bug one way or another.

 Python 2.2 (#28, Dec 21 2001, 12:21:22) [MSC 32 bit (Intel)] on win32
 Type "help", "copyright", "credits" or "license" for more information.
 >>> class X:
 ...     def __init__(self): self.s=[]
 ...     def write(self,x): self.s.append(x)
 ...
 >>> import sys
 >>> oso=sys.stdout
 >>> sox=X()
 >>> dir(sox)
 ['__doc__', '__init__', '__module__', 's', 'write']      <<--There's no .softspace yet.
 >>> sys.stdout=sox
 >>> dir(sox)                                             <<--This seems to create one before doing dir()
 >>> print 'sox ss=%s'% (sox.softspace,),    <<--This should leave softspace set IMO. Interactive EOL
 >>> print 'sox ss=%s'% (sox.softspace,),        should reset sys.__stdout__.softspace, not sox.softspace
 >>> def foo():
 ...     print 'from foo: sox ss=%s'% (sox.softspace,), <<-- these will go out with only one EOL below
 ...     print 'from foo: sox ss=%s'% (sox.softspace,),
 ...
 >>> foo()                                    <<-- single interactive EOL doesn't kill first softspace
 >>> sys.stdout=oso
 >>> sox.s
 ["['__doc__', '__init__', '__module__', 's', 'softspace', 'write']", '\n', 'sox ss=0', '\n
 ', 'sox ss=0', '\n', 'from foo: sox ss=0', ' ', 'from foo: sox ss=1', '\n']

Or, a hand-edited grouping:

 [
     "['__doc__', '__init__', '__module__', 's', 'softspace', 'write']",'\n', <<--from dir(sox)
     'sox ss=0', '\n',    <<--from 1st print 'sox... -- should have left softspace set for next print
     'sox ss=0', '\n',    <<--from 2nd print 'sox... -- but it got clobbered
     'from foo: sox ss=0', ' ', 'from foo: sox ss=1', '\n'  <<-- from foo(), note softspace not clobbered.
 ]

Looks to me like interactive typing echo should operate on the softspace attribute of the output
it's going to (sys.__stdout__.softspace ?), and not sys.stdout.softspace, unless they're the same.

Or else interactive echo characters ought to be teed/copied to sys.stdout to make the softspace action
consistent with modifying sys.stdout.softspace. I prefer the former.
