I can't see any evidence that read-conf does anything.  If I name a
nonexistant file it doesn't complain.  If I name an existing file that
does load_uftdi=YES, then doing a show afterwards doesn't show that
variable being set, and the module doesn't get loaded.

Forth is so... 1973.  I wonder what ever happened to the project to use
lua as the loader command language?
