I've hacked this approach into the CVS for pydb, but it is not all
that accurate (although in practice I'm pleased with the result).
My current regular expression is (^|\s+)exec\s+(.*) which does match
simple things, but it would fail on say by *not* matching:
x=1;exec "y=2";exec "z=3"
and fail by *wrongly* matching on:
x=" exec meeting in 5 mins"
Even if I knew how to call the python parser on the line, that still
might not be good enough in the presence of continuation lines.
This probably should be addressed at a lower level in gathering
traceback data inside Python.

^^^^^^^^
execfile is not a problem, just exec.
