I'm a little dubious about changing this behavior. As you say, it's
not like we're consistent about requiring semicolons everywhere, and
frankly I think the argument about truncated files is specious.
I've never heard of that actually happening to anybody.
What would you have it do instead? Throw an error? Silently drop
the last command (which would be the same thing, if nobody was paying
attention to the error message)? I think the compatibility lossage
from either would outweigh the benefit.
Now having said that, I've occasionally wished I could *continue*
a command across file boundaries. But I don't think it's worth the
compatibility issues it'd create.
