95 Parsing looks ahead , so we really want the previous location of the
96 lexer, not lexer_->here_input().
99 Actually, that gets very icky when there are white space, because
100 the line-numbers are all wrong. Let's try the character before
101 the current token. That gets the right result for
102 note/duration stuff, but doesn't mess up for errors in the 1st token of the line.
