Not really.  It was only by seeing Joel's change, and hence knowing that 
edge case, that I had a fighting chance of figuring out how it was ment 
to work.  BTW, even though "step_over_calls == STEP_OVER_UNDEBUGGABLE" 
is technically redundant, I think it is needed - clarifies this specific 
condition.

(Joel, perhaphs write the above as:
step_over_calls == STEP_OVER_UNDEBUGGABLE && cs->stop_func_name == NULL
since that is how the test is ordered elsewhere (since neither has a 
sideeffect it's no real difference).)
