So when I convert such a relative path to absolute,
Same logic applies? Search back (in the converted attribute) for last M|m
z|z command
and use those coords?

E.g I've converted a relative lot to
M 6 , 9876C 20, 9883 56, 9890 110, 9891
164, 9893 208, 9881 217, 9877 231, 9866 227, 9814 272, 9783
317, 9752 350, 9729 362, 9689 373, 9650 326, 9623 303, 9638
279, 9653 270, 9664 261, 9675 261, 9675 275, 9609 261, 9610
241, 9612 173, 9618 103, 9618 34, 9618 -11, 9614 -35, 9611
-52, 9622 -36, 9706 -23, 9772 -3, 9865 -13, 9869 6, 9876

and want to convert a z to absolute,
my options are L 6,9876 which appears to match your above
criteria.

Is that the right logic please? Then if I have a later z
it will still 'go home' to the same point, since the later z
reflects the first M coords?
