cmdserver: drop useless in_ attribute from channeledoutput The previous patch makes sure that in_ == out, so it's no longer needed to keep in_ for __getattr__. Also, it seems strange for channeledoutput to have in_ stream which is actually a writable file object.

cmdserver: get file attributes of 'e'-channel from stdout, not from stderr It seems wrong to get attributes from object different than the underlying file. In the following example, it doesn't make sense to flush stderr after writing to stdout: self.ferr.write(str(a)) if not getattr(self.ferr, 'closed', False): self.ferr.flush()

cmdserver: correct doc of channeledoutput in_ is only used as the source of file attributes.
