os.startfile: Why is there no arguments option?

[Christian Wutte]

Hello all,
as stated in the docs [1] os.startfile relies on Win32 ShellExecute().
So maybe someone can explain it to me, why there is no support for
program arguments.
That's quite a pity since os.startfile is the easiest way for an
elevated run (with 'runas' as option) and without arguments of limited
use.

Thanks,
