[issue1969] split and rsplit in bytearray are inconsistent

[Antoine Pitrou]

New submission from Antoine Pitrou:

In the bytearray type, the split and rsplit methods use a different
definition of what is a whitespace character. split_whitespace calls
ISSPACE(), while rsplit_whitespace calls Py_UNICODE_ISSPACE(). The
latter is probably an error since it is also inconsistent with behaviour
of the bytes type:

>>> s = b"\x09\x0A\x0B\x0C\x0D\x1C\x1D\x1E\x1F"
>>> s.split()
[b'\x1c\x1d\x1e\x1f']
>>> s.rsplit()
[b'\x1c\x1d\x1e\x1f']
>>> b = bytearray(s)
>>> b.split()
[bytearray(b'\x1c\x1d\x1e\x1f')]
>>> b.rsplit()
[]
