Add a flag to turn it off, in case weird #-marked data arises. How hard would
it be to be able to specify the comment marker as an argument? Better, as a
regular expression?

Maybe add a flag to signal whether:

1) An empty line marks EOF (that might be useful to chop data by hand), except
at the beginning
2) Empty lines are ignored
3) Empty lines are an error (except prior to EOF)

Shouldn't break anything; quoting-dequoting-overquoting is always tricky, so
users should be wary of "". Do the same for '', maybe?

Agree.
