Oh, that's exactly what is my question about. I didn't know anything
about the existence of FilterExternal.cs.

Now I see that FilterExternal is the correct way to implement this
kind of filters.

But I will improve it a bit adding a small support for regular
expressions, That will permit us to create a more powerful filter
without using a line of shell code to remove the unwanted data.
