[Csv] confused about wrapping readers and writers

These all sound fine.

You'd have to assume reasonable defaults for the other parameters.  How
about line terminator and QUOTE_{ALL,MINIMAL,NONE,NONNUMERIC} sniffers?
(Are the QUOTE_* values used by readers?)

I don't think this will be necessary.  I already added DictReader and
DictWriter classes to csv.py which do the pretty much obvious (to me) thing.

Some proofreading/editing of the PEP and the libcsv.tex file?
