Fix missing return values and some error tests for empty index files
Patches from Dave Jones and Ingo Molnar, but since I don't have any
infrastructure in place to use the old patch applicator scripts I
am trying to build up, I ended up fixing the thing by hand instead.
Credit where credit is due, though. Nice to see that people are
taking a look at the project even in this early stage.
