I am not sure startindex is worse or makes more sense than 1. If you 
have an empty nodeset, as you say, the index should in fact be 0, and 
the behavior will be incorrect whether you use 1 across the board or 
startindex.

Note that I have yet to hit a use case for startindex != 1, but that's 
probably just me?

Yup.

Yup again ;-)
