Summary: UMR in curses module

Initial Comment:
passing &char as a null terminated string
results in uninitialized memory reads

change char to char[2] and null-terminate
the array

Thanks for the report. I've checked in the AndSize version
as _cursesmodule.c 2.60, since it is the smaller change, and
since it saves a strlen call (inside FromString).

Using FromStringAndSize also fixes the problem.

I don't know which is better, but
FromStringAndSize is a smaller change
(just change the function call and 
add 1 as the second parameter)

Wouldn't it be better to use FromStringAndSize instead?
