Counting Chars by ASCI Values

In this case, we're counting delimiters - not items, so it I'm sure
it should be the number of items -1, unless we have a trailing
delimiter, when the item count and delimiter count are the same,
hence the need for "& null" or testing the last char.
This is how it seems to work on my setup (rev 2.7, Mac OS X):
1,2,3 = 3 items, 2 delimiters
,1,2,3 = 4 items (one empty), 3 delimiters
1,2,3, = 3 items, 3 delimiters - Rev doesn't count the implied empy
item at the end.
