What I've done now is to incorporate the three functions from your doc
into misc.py, but with the conditional definition approach that Peter
already agreed to.  These aren't the 'unicode'-compatible versions from
Peter's email, but since they're no longer used with Python 2 it doesn't
matter.  And the now-superfluous conditional in make_std_wrapper is gone.

I haven't yet gotten rid of the duplicate definitions in client.py; I'll
leave that for a later cleanup.

At this point, all the code is compatible with Python 2.6-2.7 and 3.2-3.5
(at least all the "normal" code; I haven't looked into devtools/ or
contrib/).  This is pushed to my GitHub, but anything requiring the C
extensions won't be easily usable with Python 3 until I add a "target
Python" feature to SConstruct.
