As Rici pointed out, zero-length matches are tricky. Conceptually, there
are infinite empty strings at any point of any string. So, the specific
behavior of a given implementation seems more a device to avoid an
infinite loop than actually a feature (or a bug). As such, programmers
should not count on that behavior.
