+The indentation tells how many periods are to be typeset if you want to be

+is free to show whatever in whatever way suits the whatsit best.

 If \prm {tracingonline} is larger than~2, the node list display will also print
 the node number of the nodes.
 
+When bit~1 of \lpr {tracinglevels} is set the current level is prepended to
+tracing lines in the log and when bit~2 is set the input level is prepended. You
+can set both bits and get both numbers prepended. In \CONTEXT\ we default to
