System queries with Lua: l3sys-query

    If openin_any is not "a" then clearly you can't read dot files but
    it isn't clear if they have to be excluded from a directory listing.

I guess I did not think about this when reviewing Nicola's texosquery
Java program. It does report dot files (using an escape syntax, but that
doesn't matter);

$ mkdir .foo
$ touch .bar
$ texosquery-jre8 -i , .
\fdot bar,\fdot foo

Therefore I conclude l3sys-query does not need to exclude dot entries
from its output.

I can't envision any particular security problem with doing so, and
clearly it has not been exploited in practice, in any case. --thanks, karl.
