Bad idea. Say foobar 1.0 is installed already. Blafase 1.0 gets
installed and triggers foobar and fails due to a bug in foobar.

Now you want to install foobar 1.1 to fix the bug.

If dpkg runs the trigers again first then it will just fail again and
again and never update to a working foobar version.
