Comment (by ericmann):

 Replying to [comment:18 nacin]:
 > Filters can be nested to create a "stack" — this is to check if the
 filter is anywhere in the stack. 14994.3.diff seems better.

 In hindsight, I see that you're right with this.  The attempt of
 14994.4.diff was to remove the dependency on a global array, but _does_
 functionally change things since using `current_filter()` will only return
 the current filter, rather than checking against all others in the stack.

 For this particular change, I think 14994.3.diff is sufficient.  In the
 future, perhaps a `current_filters()` or similar function (abstracting
 from the global) could be used as a replacement.
