The trouble with using sequences is that all the existing nmh programs
ignore order within sequences and just handle the messages in ascending
numerical order; this is pretty useless for threading and means we can't
just tweak sortm and pick. (Unless you want to maintain folders in thread
order, which would require enough intelligence in refile to insert new
messages without having to rethread the entire folder.)

Agreed.
