Alter the `dd' command in mdb so that it does not assume that the answer
to the first question asked is `no'. The question is somewhat redundant,
since the only sensible answer is `no', but I find that it gives useful
feedback about the symptom that is being diagnosed, and it makes clearer
why the following questions are asked.
browser/declarative_analyser.m:
Start analysis with a list of suspects which contains only the
topmost node of the debugging tree.
browser/declarative_debugger.m:
If the answer to the first question is something other than `no',
then end the diagnosis and report that no bugs were found.
tests/debugger/declarative/*.{inp,exp,exp2}:
Update test cases to handle the extra question.
