This is mostly to appease the compiler. -Wswitch-enum warns about
missing enumeration cases even if default is present. On the other hand
it also warns against branches that use values outside of the
enumeration (which might be useful).

Emil, any thoughts about possibly dropping this warning? I think more
people will scratch their heads if unused enumeration values need to be
added to default branch.
