If we need to add functionality to nmh to make it so commands don't modify
the sequence file and/or context, and as a result won't get a folder lock,
that seems like a reasonable compromise to me.

Of course, if you want to CALL mark inside of a hook, then all bets are
off :-)  I'm unclear how we can make that better.  I will note that rcvstore
can add messages to specific sequences, and there was a deprecated feature
where a special mh-format instruction could do the same.  We could resurrect
that feature (or something like it) if there was interest.
