Fix XML indentation in Emacs mode The return value of MATCH-STRING is a string. At least on Emacs 25, the comparisons between string and character with EQUAL could never succeed, and so the cases for matching braces were never triggered. GET-TEXT-PROPERTY may return a list rather than an atom (for example, on long lines with whitespace-mode turned on), and this broke the heuristic of looking for the tag face in previous text.

table t : { A : time }

fun many ls =
    case ls of
        [] => (WHERE TRUE)
      | tm :: ls' => (WHERE t.A = {[tm]} AND {many ls'})

task initialize = fn () =>
                     tm <- now;
                     dml (DELETE FROM t WHERE {many (tm :: [])})
