[issue2920] Patch to print symbolic value or errno in EnvironmentError.__str__()

[Antoine Pitrou]

Antoine Pitrou <pitrou at free.fr> added the comment:

PEP 3151 is already large enough and I don't want to add orthogonal changes to it. Furthermore, this change is only about the string representation of exceptions, and may be accepted for 3.2 even despite the moratorium.
