Like I said, there's at least four implementations in Emacs of the same
thing, and who knows how many in 3rd-party packages in ELPA or
elsewhere. I'm not sure what you consider "a lot," but DRY kicks in
around three times for me.

Right, I didn't mean to imply that the one I sent be added in its
current state. I just meant to kick off discussion. I basically
copy/pasted it from somewhere (lpr, I think?). If added it'll need to be
properly documented and perhaps message-flatten-list and the others made
obsolete aliases.
Thanks,
Alex
