Add option to output column headers

[cmungall]

q is a marvelous tool, thank you!

One thing that would be very useful is an option to emit column headers in the output, analogous to -H for input. These would be based on either the column names in the select, or aliases provided. Amongst other things this would allow composability of inputs and outputs.

E.g.

• SELECT * FROM my.tsv ==> preserves original columns
• SELECT a,b FROM my.tsv ==> first line is a,b
• SELECT a AS c1, b AS c2 from my.tsv ==> first line is c1,c2

Did you overlook the -O/--output-header option?
