Though not as clean as -m, this script helps.  For my own insufficiently
advanced windows box, I added a launcher batch file, pythonm.bat:

  @python \py24\tools\scripts\runpy.py %1 %2 %3 %4 %5 %6 %7 %8 %9

It runs pretty well:

  C:\tmp> pythonm timeit -s "a=range(20)" "a.append(1)" "a.pop()"
  100000 loops, best of 3: 1.75 usec per loop

  C:\tmp> pythonm regrtest test_string
  test_string
  1 test OK.

The combination of batch file and run.py isn't as good as the -m option,
but it works and mostly meets my needs.  The batch file is rather dumb,
doesn't work with other python command line options, and won't work
pipes.

Could Nick's idea be done without an -m option?  If a user types,
"python abc.py" and "abc.py" is not found, before aborting, try looking
for it on sys.path.
