updated for version 7.3.951

Problem:    Python exceptions have problems.
Solution:   Change some IndexErrors to TypeErrors. Make “line number out of
            range” an IndexError.  Make “unable to get option value” a
            RuntimeError. Make all PyErr_SetString messages start with
            lowercase letter and use _(). (ZyX)
