Summary: PyArg_ParseTuple can miss errors with warnings as exceptions

Initial Comment:
in getargs.c, the convertsimple function returns NULL
if a float warning raised an exception, for example
passing a float to an int conversion.

NULL is interpreted by the caller, converttupple, as a
NON-error

The result is that PyArg_ParseTuple returns TRUE even
though it has left the float unconverted (and the
receiving integer variable containing whatever garbage
it contained before the call)

changing the return on the float error from NULL to
"converterr("integer<i>", arg, msgbuf, bufsize);", as
is done with every other error in this function,
corrects the problem.
