When opening a CSV file, the field number in the modeline is initially
displayed as 'F0', if I move point past the first character it get's
updated to F1. This behaviour repeats for every other field in the csv
file. So If I am in the buffer at the frist character of field 5 it is
still reported as F4, if imove to the second character of field 5
it is correctly reported as F5.

I've now fixed this in GNU ELPA, so the fix should show up within a day.
