trace/mercury_trace_cmd_browsing.c:
Change the dump command to allow the name of the variable
whose value is to be dumped to be followed by a path,
specifying the *part* of the variable's value to be printed.
trace/mercury_trace_vars.[ch]:
To make that possible, provide a version of an existing function
that returns an extra value that the new code in
mercury_trace_cmd_browsing.c needs, and another extra value
that conceptually belongs with it.
Mark strange code with an XXX.
NEWS.md:
Announce both this new capability and a just-now contributes predicate.
library/pqueue.m:
Make the just-now contributed code more readable.
tests/debugger/browser_test.{m,inp,exp3}:
Extend this test case to test the new functionality.
