[Message part 1 (text/plain, inline)]

In scss-mode, Font Lock hangs on particular instances of Sass lists.
To see an example of this, paste the following into a buffer, and
activate scss-mode + font-lock-mode:

$list: (
   ('string', #000000, #fff)
   ('string', #000000, #fff)
   ('string', #000000, #fff)
   ('string', #000000, #fff)
   ('string', #000000, #fff)
   ('string', #000000, #fff)
);

Font Lock hangs, and I find that I have to press C-g a number of times
to be able to continue editing.

It seems that this happens because scss-mode thinks that the list
elements are selectors. The attached patch attempts to fix this by
disallowing parenthesis in selectors, except for in the function
notation that might appear right after pseudo-classes.
