Thank you Wolfgang for the quick diagnosis and Hans for the fast turnaround.
Sorry, I was wrong about the turnaround -- I tested on my own patched copy, not the new download, but I am sure it will appear soon.
Follow-up question. Can protrusion be implemented in the first line of a footnote or endnote, as might improve the following? I have some page-long endnotes that benefit from having it in place, but do not like the inconsistent appearance.
Please excuse the hokey example:
\setuplayout [width=9cm,
height=9cm]
\definefontfeature [default]
[default]
[protrusion=quality]
\setupalign [hanging]
\setupquotation [method=font]
\setupnote [endnote]
[location=none]
\setupnotation [footnote]
[align=hanging]
\showframe
\starttext
\quotation{{\em Cantharides}} is the reported message from Sir Francis
Drake upon defeating the Spanish Armada.\endnote{\quotation{{\em Vovi}} is
reportedly the message from James Broun|-|Ramsay on taking Oudh. Both
are as likely as the attribution of \quotation{{\em peccavi}} to Napier after
his defeat of the Ameer of Scinde.}\footnote{\quotation{{\em Vovi}} is
