Just to follow-up to this and at the same time address Kurt's question, 
clearing "new" effectively does so too.  So
   <tag-pattern>~U<enter><tag-prefix-cond><clear-flag>N
would work just as well.

Internally, Mutt uses two different bits, "old", and "read" to represent 
the three states.  "<clear-flag>O" sets the read bit and unsets the old 
bit, while "<clear-flag>N" only sets the read bit.  However, Mutt 
patterns and display flags ignore the old bit if read is set.
