Confusing error Do not allow except col_sep_split_separator

[elfotografo007]

Is it possible to make the following error message less cryptic? I have no idea what is col_sep_split_separator (It doesn't appear in the documentation or in the parameters), and the language is not clear at all:

csv/lib/csv/parser.rb

Line 687 in 000221d

message = "Do not allow except col_sep_split_separator " +

In the past CSV.parse('"a"bc"') returned "CSV::MalformedCSVError: Unclosed quoted field on line 1.", which states clearly that a quote is unclosed.

Now, it returns "Do not allow except col_sep_split_separator after quoted fields in line 1.", and I think most people wouldn't know what is causing the problem.

Thanks for your report.
I've improved the error message.
