Repeated spam registration

[David Hanak <dhanak-9Zn/qaPSiLf0Rh6LxjfsapVzexx5G7lz@public.gmane.org>]

Hi,

I use spam.el with bogofilter to filter spam with great satisfaction.
There is one minor detail, though which is bothering me.  Every once in
a while I have to go back to old, read mail and read it again.  These
messages are ususally already marked as ham.  After I reread them and
exit the group, they are obviously marked as read, which is a ham mark,
so they are *reregistered* with bogofilter.  Because I use the registry
to remember spam classification, they are duly unregistered before the
reregistration.  So this is what I get in the *Messages* buffer:

,----[ *Messages* ]
| Unregistering 1 specific articles as ham using backend spam-use-bogofilter
| Registering 1  articles as ham using backend spam-use-bogofilter
| 1 ham messages were processed by backend spam-use-bogofilter.
`----

This is of course slow and completely unnecessary.  I tried adding the
ancient-mark to the list of ham-marks, but that only resulted in the
omission of the unregistration, the reregistration was still done, which
is obviously worse.  Is this how it is supposed to work?  Is there a way
to solve this problem?

Thanks,
