Description
The following line:
$( '.hlist dl dl, .hlist ol ol, .hlist ul ul' )
.before( '( ' ).after( ') ' );
Throws an exception in IE7 if the the query returns empty, passing null to before() and .after(). IE8 and other browsers does not have this problem.

It's actually failing everywhere, you can see the console error thrown by Sizzle.error in Chrome for example. It's a simple fix so I'll get it now.

I discovered indeed it happens in all browsers. The problem is in combination with the text passed ("( "). Passing "<span>( </span>" instead does not fail.

It appears to happen on any combination of characters (brackets and operators) that have any meaning in javascript. "*" is especially fun... .append() and .prepend() are not affected.
The best fix is to not do anything when applied to null.

Fix #10812, let .before() and .after() work on empty collections.
