I think the output looks spot on and the tests cover the twelve ways of
combining 3 × 2 × 2 settings.

    Sequence: all existing existing-and-non-existing
    Message: all stated
    Empty: empty noempty

What if ‘uip/mark -l 42’ is done where 42 doesn't exist?  I think that
should complain 42 doesn't exist to be consistent with a mark to add to
a sequence, or a scan of it, and you probably get that behaviour ‘for
free’, but I'm just checking.

Sorry for the extra labour, I realise it's easier to just heckle and lob
empty beer bottles.  :-)
