imapfilter progress (?)

I made a little progress (?) on this issue yesterday:
https://sourceforge.net/tracker/index.php?func=detail&aid=1653494&group_id=61702&atid=498103
and attached a patch that should help by giving more explicit
diagnostics.  One strange thing I've noticed is that when I set an
explicit ham folder, nearly every message moved there ends up being
marked "deleted."  I can't see anything in the code that would explain
that behavior. Does anyone else?

Thanks,
