[NTG-context] ending every paragraph

Dear gang, Suppose I want to end the last line of every paragraph with a command, say, \thinrule, or a string of dots. Is there a straightforward way to do that? TeX has \everypar but I'm not aware of any, say, \endeverypar command. Best wishes Idris -- Idris Samawi Hamid Professor of Philosophy Colorado State University Fort Collins, CO 80523
