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 : int}

fun main () : transaction page =
    () <- dml (INSERT INTO t (A) VALUES (0));
    return (error <xml>No way, Jose!</xml>)
