Summary: SystemError with re.match(array)
Initial Comment:
An small issue which I guess is to be found in
the implementation of the buffer interface
for zero-length arrays:
>>> a = array.array("c")
>>> r = re.compile("bla")
>>> r.match(a)
SystemError: error return without exception set

It seems to me that an empty array should be
equivalent to an empty string. Accessing it as a
buffer should return a buffer of length 0, not
raise ValueError.
In all cases, the fix in _sre.c is sensible.
