The following fails in Py3.0a5:

>>> import re
>>> re.search(b'(\d+)', b'-2.80 98\n')

I get a TypeError: "Can't convert 'int' object to str implicitly" in
line 204 of file "sre_parse.py", code being "char = char + c".

I think it's debatable whether re should byte strings since it is
searching through text and not raw binary data. However, this may be a
case of practicality over purity.

Ah, I now see what the actual problem is. Byte strings return the byte
value on indexing.

Changing the title accordingly.
