AnaGram interim repo (temporary): examples/dsl/query.cpp annotate

annotate examples/dsl/query.cpp @ 8:ec2b657edf13

Add explicit lint-comment-style fallthrough annotations. GCC now assumes that if you don't have these you're making a mistake, which is annoying. XXX: This changeset updates the AG output files only (by hand) and is XXX: abusive - rebuilding them will erase the change. However, I need XXX: to get things to build before I can try to get AG to issue the XXX: annotations itself, so this seems like a reasonable expedient.
