Dale Nagata has a cute one-liner for this; see

The bug he reported there (tracebacks are off by a line when using -x)
didn't get fixed in time for 1.5.2, alas; it is fixed in the development
version.  Note too that parts of Dale's method require that you're running
NT and have "cmd extensions" enabled (which is the default, so don't worry
about it if it doesn't make sense).

It's more useful for certain kinds of .exe's, where it can be convenient to
run a .bat file to fiddle system properties before the .exe gets run.
Usually see it only in programs with deep Windows backward-compatibility
problems.
