The following gets it into a bad state:
(i) Set up two separate valid raw strings with the same delimiter in
  both.
(ii) "Damage" the closing delimiter of the first string.  There is now
  just one raw string which extends to what used to be the end of the
  second raw string.
(iii) Restore the closing delimiter of the first string.  The
  syntax-table text properties and fontifications are now broken, and, I
  think, need the mode reinitialising to recover.
