ohhh ... indeed! when i fixed the code on Ralph's instructions, i
finally was able to slurp a whole file and discovered a emtpy entry at
the end of the flow so i realize that \n is actually a terminator, not
a separator.

This grammar really was an exercice. I also wrote a really simple csv2tsv
in C which is really fast and was actually simpler to write.
