REX Does Not Return Redundant Empty Hits - Caveat

In version 7 and later, REX no longer returns certain theoretically-correct but redundant empty hits. For example, searching for the expression "a*" against the data "a" used to return two hits - "a" and "" (empty string at the end of buffer); in version 7 only the first hit is returned. More specifically, hits are skipped where the entire match (including any \P and \F parts) is empty and adjacent to the previous entire match.
