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.
