pandoc lua vs. pandoc

Is there any global value which is guaranteed to have different values when
running as `pandoc lua` vs. running as `pandoc`?

My use case is a script which should work both as a filter and as a
standalone script and print some info in the latter case.

It seems like `PANDOC_STATE` is nil when running as `pandoc lua`, but is
this always so, and/or is there a better option?

The `PANDOC_STATE` variable being nil might be a bug, I'll have to check
that. The `arg` global should be a good indicator: it will always be set
to a table value when running `pandoc lua`, but never in filters or
custom readers/writers.
