A couple thoughts:

* This test needs to appear further down --- it is not sensible until
after you've checked strlen() == 1 for all the strings involved.

* I see that we disallow the CSV quote character from appearing in the
null_print string, but not the escape character.  Is this
correct/sensible?  If it is correct, maybe the delimiter could also
match the escape character?
