Hello,
I am impressed by the activity here. I am a new programmer and cutting my teeth
with python. I wish I knew how to do a patch and write unit tests, but I'm just
not there yet.
I can show a test case in this fashion where it fails.
First I prove that /bin/sh is /bin/sh (er, dash) and /bin/bash is /bin/bash.
Then it can be seen that when executable is set as /bin/bash and there is a
shell error, that it returns a shell error from /bin/sh, not from /bin/bash.
I see there are patches here that should fix it, but for those wanting to see
the buggy code in action, here it is using the fact that echo was mistyped as
echos to raise a shell error (but shell=True so it doesn't raise an OSError
exception).

>>> shell = Popen('echos', shell=True, executable="/bin/bash", stdin=PIPE,
>>> stderr=PIPE, stdout=PIPE)
>>> shell.communicate()
('', '/bin/sh: echos: command not found\n')
>>> shell = Popen('echos', shell=True, executable="/bin/bash", stdin=PIPE,
>>> stderr=PIPE, stdout=PIPE)
>>> shell.communicate()
('', '/bin/bash: echos: command not found\n')
Thank you for working on this so quickly. This is truly an amazing community.
