Subject: [PATCH] SyntaxError's filename and lineno may be undefined. (#3918)

The Python source (Objects/exceptions.c) explicitly checks for null
pointers before using the filename and lineno members. Some libraries,
e.g. pkg_resources, set filename and lineno to undefined values if
indeed none are appropriate.
