Closing bug #12 because the error messages themselves are at least better,
but detection isn't perfect. (Which is why the "Maybe missing a semicolon?"
has a question mark at the end.)

Please add example.

this is another one where it's just a matter of taking a couple of the
built-in examples and removing semicolons to see how it chokes. the antlr
message is being trapped, but the result is a split problem: 1) the message
is ugly, so it's being caught and altered to be a little friendlier, but 2)
since it's not always b/c a semicolon is missing, it can't just say
"missing ;" instead it's got that ? at the end. which isn't just because
the preprocessor as a passive and friendly character.
