bug#29967: 24.5; Bash syntax highlighting: wrong closing double quote mark

[Sam Kuper]

--text follows this line--

- Run `emacs -Q emacs_syntax_highlighting_bug.bash` (the latter file is
  attached).

- Note the double quote mark on line 5.

- Emacs incorrectly assumes that the corresponding closing double
  quote mark is the one on line 10, but in fact it is the one on line 11.

- As a result, the rest of the script (i.e. beyond the double
  quote mark on line 10) has incorrect syntax highlighting.
