[Configobj-develop] Possible empty list value parsing bug in ConfigObj

[<ale...@se...>]

I've been hoping to use configobj to read database field parameters into a
script using configobj. Preserving the order of keys and in built list
handling make it a very nice fit.

I've come up against a parsing error, when a list contains an empty value
represented by 2 adjacent commas (i.e. ,,)

ConfigObj({'Fields': {'Name': ['TEXT', '0', '0', '100', 'NULLABLE',
'NON_REQUIRED']}})
>>> configobj.ConfigObj('tmp2.ini')
Traceback (most recent call last):

    raise error
ParseError: Parse error in value at line 2.
>>> for line in open('tmp.ini'): print repr(line)
...
'[Fields]\n'
'Name = TEXT,0,0,100,NULLABLE,NON_REQUIRED,\n'
'\n'
>>> for line in open('tmp2.ini'): print repr(line)
...
'[Fields]\n'
'Name = TEXT,0,0,100,,NULLABLE,NON_REQUIRED,\n'
'\n'
>>>

Should this be submitted as a bug, or should I be putting quotes around all
empty values?
