delete chunk.

[Mike Bonner]

Hmm. I get your point, and now I think I have a little bit of gray leaking
out my left ear.  If you look at it as if the delimiter is both an
instigator AND a terminator, then if you have a var with "," in it, it seems
like it should be 2 empty (and pointless) items. I had been thinking that it
could be considered an instigator only with an assumed delimiter before the
first item, but then as you say, empty isn't empty, empty would be 1 empty
item.

This also explains why I will never ever write my own intepreter/compiler.
Too many things I will never understand well enough. Love trying to get my
head around things, failure to do so can be as educational as success if not
more so.
