Comment:

 While using this functionality I realized something strange. To get an
 extra argument (say for 'bloginfo' filter) I have to specify not 2 but
 actually 4 in add_filter. The returned data are:
 first argument, filter name, first argument, second argument

 BTW: One place where this function is needed is for writing 'bloginfo'
 filter. It passes two arguments - value and key.

 So when I add_filter I have to write:
 add_filter('bloginfo', 'my_filter',10, 4 );

 And then I access the second argument as:
 function remove_css($first_argument,$dummy,$dummy,$second_argument)

 I haven't tried for more than 2 arguments but I suspect it will be equally
 funky.
