AW: Experimenting with pandoc module using just Lua

[<denis.maier-NSENcxR/0n0@public.gmane.org>]

IDK if the use case is common enough to warant a new command line parameter...

But, what about a new option like this?

`pandoc -L build.lua --no-input`

The example `echo '' | pandoc` works with Powershell, but not with cmd. There you'll get the result:
<p>ÔÇÖÔÇÖ</p>

Don't know about bash or other shells.
