Just to double check, the thing I found odd was that it broke some
indentation, but not all. I don't know anything about how it works or
what its impact is, but it wasn't like it disabled indentation across
the board. It just made much of the indentation stop working or break
in subtle ways.

This is what smie-config-buffer-local ends up as: ((-5 :elem basic 2))

Thanks,

Aaron
