Interactive hosts expect an `IncompleteParseException` to signal that more input is expected. When detecting errors, the parser can report 2 positions: * where the error should be reported * where the error was detected Typically these are the same, so most error reporting methods have a single parameter. For missing braces, the pattern is supposed to be to report the error after the opening brace, but the error is typically detected at the end of the file. There were a few places where we were not consistent in reporting such errors, this PR corrects those places.
