[issue5329] os.popen2 and os.popen3 in python 2.6 incompatible with os.popen* in python 2.5

[Jani Hakala]

New submission from Jani Hakala <jahakala at iki.fi>:

The implementation in python 2.6 expects the cmd argument to be a string. 
The documentation - help(os.popen3) - states that the cmd argument can
be a sequence on Unix.

This difference may cause programs that work with python 2.5 to fail
with python 2.6

I have tested the patch attached with one of my scripts that failed with
python 2.6 and the fix appears to work.
