This is a
disclaimer to my former message about this subject.
I continued
considering the solution to the problem of using *fleurons* in a
document via the suggested *\leaders* command and it turned out to be a
dead end for the following reasons:
1) it acts wrongly if the page in which the *fleuron* is to
appear has a lot of blank space availabe, as the following test code
demonstrates:
\setuplayout[lines=30]
\def\Fleuron
{\par
\leaders\vbox
to \lineheight{\midaligned{Finis\\coronat\\opus}}\vfil} \starttext
\dorecurse{32}{Line \recurselevel\par}
\Fleuron
\stoptext
where
the intended *fleuron* appears superposed several times instead of the
only one desired;
