Oh dear, that was half-baked thinking.
Markup lists have tripped me up yet again.

It is normal 'automagic' for
   \box { "X" "Y" "Z"}
to be mapped into
   { \box "X" \box "Y" \box "Z" }
giving you 3 boxes in a markup list
to which \concat can be applied.

So that mapping mechanism will do the same for
   \general-align Y UP
as it does for \box.



The non-mapping cases
   \markup \box \concat { "X" "Y" "Z" }
and
   #(markup #:box #:concat ("X" "Y" "Z"))
give one box without complaints


The mapping case
   \markup \concat \box { "X" "Y" "Z" }
gives 3 boxes without complaint, but
   #(markup #:concat #:box ("X" "Y" "Z"))
is errored.

Reformulating it as
   #(markup (make-concat-markup (make-box-markup ("X" "Y" "Z"))))
is also errored.

And here I get stuck, just like the markup-list does.
