Yes.

I don't really care; I guess we can leave the X-Scanned-By: header alone.
People who absolutely want it inserted at the top can suppress it with
the -X option and then add it in using some Perl code.

Sounds great!  A lot of the code for action_insert_header will be the
same as for action_add_header, so there's opportunity for refactoring there.
If you want to make a first-pass at it, I will take a look and clean
it up if necessary.

One annoying issue is that I can't see a way to feed back to the Perl code
whether or not action_insert_header is even available.  We have no way
from Perl to query the milter capabilities or milter version. :-(

David.
