Plus footer set to off. So --csv would be like
\pset format unaligned
\pset fieldsep ','
\pset footer off
\pset unaligned_quote_character '"'

I guess we'd add a \csv command that does these together.

There would still be some discomfort with some of the issues
discussed upthread. For instance
  psql -F ';' --csv
is likely to reset fieldsep to ',' having then a different outcome than
  psql --csv -F';'

And there's the point on how to come back from \csv to another
output, given that it has overwritten "footer" that is used across
all formats, and fieldsep used by unaligned.
So a user might need to figure out anyway the
intricaties behind \csv, if it's not an independant format.

On the whole I'm inclined to resubmit the patch with
fieldsep_csv and some minor changes based on the rest
of the discussion.
