In "print_trace_enter", for a
Closure { "cbname" }
arg, we create the format string
cbname=<fun>
and (accordingly) we don't create a value to print.
This is a problem for a subsequent patch. When we iterate over the values
to format, it's only the Closure pattern that does not invoke "pr"; all
other patterns result in a "pr" call.
In order to handle a Closure arg uniformly with the other types, reuse the
logic seen with the OClosure optarg pattern. Namely, create the format
string
cbname=%s
and create the value
"<fun>".
