Another updated version.
I have changed the configuration setting to backtrace_functions plural,
so that you can debug more than one location at once. I had originally
wanted to do that but using existing functions like
SplitIdentifierString() resulted in lots of complications with error
handling (inside error handling!). So here I just hand-coded the list
splitting. Seems simple enough.
I think this patch is now good to go from my perspective.
