Summary: CSV reader does not parse Mac line endings

Initial Comment:
#Test code:

import csv
import traceback

class excel_mac(csv.Dialect):
    delimiter = ','
    quotechar = '"'
    doublequote = True
    skipinitialspace = False
    lineterminator = '\r'
    quoting = csv.QUOTE_MINIMAL
csv.register_dialect("excel_mac", excel_mac)

class excel_unix(csv.Dialect):
    delimiter = ','
    quotechar = '"'
    doublequote = True
    skipinitialspace = False
    lineterminator = '\n'
    quoting = csv.QUOTE_MINIMAL
csv.register_dialect("excel_unix", excel_unix)

testdata = range(10)

for dialect in ["excel","excel_unix","excel_mac"]:
	try:
		print '\n Testing dialect "%s"' % dialect
		test = file('test.csv','w')
		writer = csv.writer(test,dialect=dialect)
		for i in range(3):
			writer.writerow(testdata)
		test.close()
		
		test = file('test.csv','r')
		reader = csv.reader(test,dialect=dialect)
		for row in reader:
			print row
	except:
		traceback.print_exc()
