Documenting this better would be a good idea.  I'll try to do get it
done for the next release.  Patches welcome.

If both ignore_tags and report_tags are set then they both filter out
events and ignore_tags effectively takes precendence.  For example:

   $p->ignore_tags("a");
   $p->report_tags("a", "b");

Only "b" will be reported.  This should probably also be documented
better.
