That's an interesting thing. Ideally I would prefer the query command do
exactly what I asked, if I asked about existence of some path, I would
like to check that path and tell me which package brought it to my box. In
an idiotic situation when symlink came with one package and actual file
symlink points to from another, when I query symlink, I'd like to get an
answer about it. Am I missing something?
