`pick unseen 42' does a union of both.  There's no `-inseq unseen'
option to pick.

There's

    pick -seq foo 42 314
    mark -seq foo -del notunseen
    pick -list -seq foo
    mark -seq foo -del all

`not' is my ~/.mh_profile's `sequence-negation: not'.  The second pick
might complain `foo' doesn't exist and exit(1).  If it doesn't, you can
clean up with the second mark.

Given it's cleaning up, I think the above is OK with foo being the UUID
equivalent for an MH sequence name.  :-)  Note, if the user has `pick:
-seq lp' in ~/.mh_profile, or similar, then your uses of pick, etc.,
might affect that global state anyway, e.g. `lp' value, unless steps are
taken to avoid it.

Cheers, Ralph.
