Commenting out the \page_grd_command_flush_page macro seems to have
reversed the effect. Any pages having columnar text that does not
extend to the last line are now suppressed. How would I go about
adding a conditional that checks to see whether the column is filled
before deciding if a page break is necessary?
\unprotect
\def\page_grd_stop{%
\endgraf % needed, else wrong vsize in one par case
\vfill % otherwise weird \placenotes[endnotes]
\page_grd_command_set_vsize % needed
\penalty\c_page_otr_eject_penalty
%\page_grd_command_flush_page
\page_otr_fill_and_eject_page
\page_grd_command_set_vsize % why here
\egroup
\page_otr_command_set_vsize
\page_otr_command_set_hsize}
\protect
Fails for the next example (the first page appears twice in the PDF and
the second page is missing):
\setuplayout[grid=yes]
\starttext
\startcolumnset[n=2]
\dorecurse{100}{Line #1\par}
\stopcolumnset
\stoptext
