Instead of creating, multiple sequences, I use a script which just
creates a single sequence given a message number to start with. It's a
zsh function I'm afraid. Cut down to the essentials, it is as follows:
local -a msgs refer ref rep mid
msgs=( ${@:-cur} )
ref=( $(scan -width 2048 -format '%{in-reply-to} %{references}' $msgs) )
mid=( $(scan -width 256 -format '%{message-id}' $msgs) )
(( $#ref )) && refer=( '--message-id '$^ref )
(( $#mid )) && refer+=( '--references '$^mid '--message-id '$^mid
'--in-reply-to '$^mid )
pick ${=${(j: -or :)refer}}
As far as I can see, this doesn't handle the situation where none
of the messages have References: and instead you have to a follow a chain
of In-Reply-To:. That's the sort of thing which makes threading
non-trivial.
Cheers,
