I personally like this functionality and would miss it if it's gone
for good.  It's EXTREMELY useful when you're trying to trace the
program to see when you get out of a particular call tree by
looking at the indentation level.  It's most helpful when you have
a re-entrant function.

I think I like the log-level test short->long, because it means
if I set e.g. "gnc" -> debug then I get ALL "gnc.*" messages,
even if gnc.foo.bar is set to "error"..
