py3: rename test-check-py3-commands.t to test-py3-commands.t test-check-*.t is a set of tests which tests certain coding style checks. So this test was wrongly named, thanks to marmoute for pointing this out.

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!

py3: use pycompat.byteskwargs to converts kwargs to bytes baseformatter._item must contain both keys and values in bytes. So to make sure that, we convert the opts back to bytes.

py3: make adefaults keys str to be compatible with getattr getattr passes a str value of the attribute to be looked and keys in adefaults dict are bytes which resulted in AttributeError. This patch abuses r'' to make the keys str.

py3: abuse r'' to access keys in keyword arguments

py3: use pycompat.bytechr instead of chr

py3: use %d to format integers into bytestrings

py3: use pycompat.bytestr instead of bytes

py3: slice over bytes to prevent getting ascii values

py3: use encoding.unitolocal instead of .encode(encoding.encoding)
