Maybe so. A bit of a pain to revise all FILE-related function calls in
csvdata.c to use the gzFile API, but certainly feasible.
There's now a csv_gz branch in git, with support for reading
*.csv.gz, and also writing gzipped CSV if the output file has
extension .csv.gz. On the writing side I guess we need to decide if
the --gzipped option should be supported for CSV, and if so what
exactly to do with the filename: add ".gz" is it's not already
there?
I haven't made the changes in master at this point just in case
any problem emerges with reading non-gzipped CSV (though I think
we're OK in that regard).
