;; the last test in the above and is because some syntax objects
;; appear to be from the original source, but can have bogus information.
;; Use (add1 end) below, because interval-maps use half-open intervals
;; ie, [start, end] = [start, end+1)
;; interval-maps use half-open intervals which works out well for positions
;; in the editor, since the interval [0,3) covers the characters just after
;; positions 0, 1, and 2, but not the character at position 3 (positions are
;; between characters)
