In Rev, using space as an itemdelimiter works as you'd expect:

set the itemDel to space
put the number of items in "a b c" -> 3
put the number of items in "a   b c" -> 5

However, the "word" function will still only return the actual number of 

put the number of words in "a     b c" -> 3

which is generally what we want.
