The purpose of the -m option is that you can run a script that is
located via the Python import path instead of an explicit file path.
The idea is that if '/path/to/somewhere' is in sys.path then:
    python -m script arg1 arg2
is equivalent to
    python /path/to/somewhere/script.py arg1 arg2

If Python didn't modify sys.argv then 'script.py' would need to be
rewritten to understand that sys.argv would be in a different format
when it was invoked using the -m option.

I believe that it has previously been proposed to include something
like sys.raw_argv, although perhaps for different reasons. Although
something that might be more useful to the OP (and that I at one point
wanted) would be a function similar to execfile but that would launch
a separate process using the same interpreter as the current process.
