Summary: csv writer bug on windows

Initial Comment:
The excel dialect is set up to be
class excel(Dialect):
    delimiter = ','
    quotechar = '"'
    doublequote = True
    skipinitialspace = False
    lineterminator = '\r\n'
    quoting = QUOTE_MINIMAL
register_dialect("excel", excel)

However,  on the windows platform, the lineterminator
should be simply "\n" 

My suggested fix is:

class excel(Dialect):
    delimiter = ','
    quotechar = '"'
    doublequote = True
    skipinitialspace = False
    if sys.platform == "win32":
        lineterminator = '\n'
    else:
        lineterminator = '\r\n'
    quoting = QUOTE_MINIMAL

Which seems to work.  It could be that I'm missing
something, but the universal readlines doesn't appear
to work for writing files.  If this is a usage issue,
it probably should be a documentation fix.
