When the lexer chokes on a stray character, its shows the characters until the next structural character in the error message. It uses a regular expression to match a non-empty string of non-structural characters. Bug: the regular expression treats '"' as structural. When the lexer chokes on '"', the match fails, and trips must_match()'s assertion. Fix the regular expression.
