[Bug-datamash] Output field separator switch?

[Dave Myron]

I'm late to the game discovering GNU datamash but it's fantastic! 

One thing I've found strange is that passing in the field separator also impacts the output. 

For example, with a CSV file I, obviously, give -t, but that also causes datamash to print its output with a comma separator. This is surprising to me.

$ datamash -sHt, -g5,6,7,8 count 1 < myfile

GroupBy("delivered"),GroupBy("clicked"),GroupBy("control_persistent"),GroupBy("control_campaign"),count("subscriber_id")

"N","N","N","N",180352

"N","N","N","Y",1199

"N","N","Y","N",802

"N","N","Y","Y",68

"U","N","N","N",52269

"U","Y","N","N",392

"Y","N","N","N",337929

"Y","Y","N","N",17515

Ideally, it'd still print out "normally", ala:

GroupBy("delivered") GroupBy("clicked") GroupBy("control_persistent") GroupBy("control_campaign") count("subscriber_id")

"N" "N" "N" "N" 180352

"N" "N" "N" "Y" 1199

"N" "N" "Y" "N" 802

"N" "N" "Y" "Y" 68

"U" "N" "N" "N" 52269

"U" "Y" "N" "N" 392

"Y" "N" "N" "N" 337929

"Y" "Y" "N" "N" 17515

Of course, I can "fix it" by piping the result into column -s, -t and get things nicely laid out again.

Would it be possible to get a separate output field separator switch?

Thanks,

Dave Myron
