System queries with Lua: l3sys-query

[Karl Berry]

    texosquery won't show any dot files or any symlink to a dot file with 
    openin_any = r (or p)

Ah. Sorry I failed to test correctly. That behavior sounds sensible to me.
Ok, Joseph/David? 

    I don't know how big a concern symlinks to dot files are.

I wouldn't say "great" concern, since it's never happened in our world
afaik, but it seems right to omit them too. --thanks, karl.
