How to properly exclude the parsing of :first-child for IE7/8 ?

[Ian Y.]

I edited the value of var RE_PSEUDO_STRUCTURAL to the following one for IE7/8 in order to exclude the parsing of :first-child for IE7/8.

/^:(empty|first-of-type|(last|only|nth(-last)?)-(child|of-type))$/;

However, the following selector then being ignored.

li:not(:first-child) { ... }

How to properly edit the regexp's so that we don't have to parse :first-child for IE7/8 while keep :not(:first-child) working?
