Subject: bug#22224: 24.5; In opascal-mode If backslash was the last symbol in a string literal the parsing error occures

If backslash was the last symbol in a string literal the parsing error
occured. E.g. after such a line in pascal
code - "const baseDir = 'C:\';", - all following code was faced as string.

You can reproduce the problem this way:
> emacs -Q

C-x b 1 RET
write following text in a buffer "1":
"""
const baseDir = 'C:\';
var x: integer;
"""
M-x opascal-mode RET
C-r var RET
C-u C-x =

in *Help* window you can see the line:
  face                 font-lock-string-face
but must be:
  face                 font-lock-keyword-face​​

I put a patch to resolve the problem (see attachment to this emal message).
