we *should* be using it, save that it has two bugs (described next) which
limit our use of it. When these bugs are fixed, this function should be
forsaken in favor of direct use of the csv module (or similar).
The basic use case is to split a function signature string, so for:
afunc(arg1='str1', arg2='str, with, embedded, commas', arg3=7)
we want a 3 element sequence:
["arg1='str1'", "arg2='str, with, embedded, commas'", "arg3=7"]

6 ["arg1='str1'", "arg2='str", 'with', 'embedded', "commas'", "arg3=7"]
which we can see is not correct - we wanted 3 tokens. This occurs in
Python 2.5.2 and 2.6. It seems to be due to the text at the start of each
token ("arg1=") i.e. because the quote isn't for the whole token. If we
were to remove the names of the args and the equal signs, it works:
>>> x = "'str1', 'str, with, embedded, commas', 7"
>>> rdr = csv.reader( (x,), dialect='excel', quotechar="'", skipinitialspace=True)
>>> l = rdr.next(); print(len(l), str(l)) # doctest: +SKIP
3 ['str1', 'str, with, embedded, commas', '7']
But even this usage is delicate - when we turn off skipinitialspace, it
fails:
