The syntax "raise a, b, c" and "raise a, b" are invalid in Python 3.
To be compatible with Python 2 and Python 3, this change:
* Replace "raise exc[0], exc[1], exc[2]" with "six.reraise(*exc)"
* Replace "raise exc_type, exc_value, exc_tb" with
"six.reraise(exc_type, exc_value, exc_tb)"
* Replace "raise exc, msg" with "raise exc(msg)"
This patch was generated by the sixer tool version 0.2 with the "raise"
operation:
