Tracing is so much easier and better than io format! Though it needs
to be as simple as:

trace_function(Mod, Fun)

The stuff in e2_debug took a fair amount of effort for me to divine -
but even with that knowledge, I surely don't want to mess with
anything more than a single function call.

I also spent a fair amount of effort in getting the output to be
usable (for me). Small details perhaps, but if I didn't have that
facility as it is, I'd be an ioformatter :)
