If they were legal, we'd have to decide what they did. And specifying tab 
handling is a big fat nuisance. :)

Interpreters should not shut down in protest (unless they are set to a 
very high level of error-checking, which non-developers will generally not 
use.) Obviously the conservative path is to render a tab as "some 
whitespace", but we don't want to encourage new games to rely on this, so 
we declare it illegal.
