Looks like it got fixed in this commit:

http://git.savannah.gnu.org/cgit/emacs.git/commit/?
id=47e9556c70a7009d7c750fd7bf10a0e6cf41cdce

 
- (sql-add-product-keywords 'ms
-  '((\"\\\\b\\\\w+_t\\\\b\" . font-lock-type-face)))
+ (sql-add-product-keywords \\='ms
+  \\='((\"\\\\b\\\\w+_t\\\\b\" . font-lock-type-face)))

But while grepping for "’\([a-z(]+" in the emacs repo base dir, I found 
just this one case that yet needs to be fixed:

Line 1013 of htmlfontify.info

     ’((class color grayscale) (type tty)) would match any of:
            '((class color))
            '((class grayscale))
