py3: use list of bytes rather than bytestring while extending bytes into lists

Python 2:

>>> ls = []
>>> ls.extend(b'abc')
>>> ls
['a', 'b', 'c']

Python 3:

>>> ls = []
>>> ls.extend(b'abc')
>>> ls
[97, 98, 99]

So to make sure things work fine in Py3, this patch does:

>>> ls = []
>>> ls.extend([b'a', b'b', b'c'])
>>> ls
[b'a', b'b', b'c']

After this `hg log -G` works!
