That would give him
{"1","","","2","","4","","5"}

You can't very well ask to toss the first delimiter and keep the remaining
delimiter in
your example. But anyhow, from the html doc for strtok:

New in v2.1 is "k" for keeping the separators in the parsed nested sequence, and
"i" for case insensitivity in comparing alphabetic strings (see the last 2
examples).
You can use "k" and "i" at the same time.

parse("nick!ident at a.net",{"k","!@"}) = {"nick","!","ident","@","a.net"}
