Remind me ... how many parsing languages get fired up for a random Unix
command on a modern Unix system, today? :-)

But, okay, that's not really fair.  The mh-format language is, I think,
pretty lightweight in terms of embeddable languages.  Probably more
problematic is I think scan(1) opens the message even though it
doesn't need anything from it.

I think that would make sense to me; I cannot think of a reason why that
wouldn't generally be useful.
