Are you implying that the bug is in the length function?  Or the way Rev
evaluates an item chunk?

If you type 4 spaces into a field, the length function applied to that field
will return 4.  If you place a comma and 4 spaces in a field, and get the
number of characters of item 2 of the field, Rev will return 4.

Not sure what you're seeing as a bug.
