Okay.  I didn't think about backward compatibility.
I've reverted my change.

One comment from Ikumi-San.
  dviout for Windows works with TeX-run-discard.
And he suggests renaming TeX-run-dviout to TeX-run-discard-foreground,
TeX-run-dviout should be alias to TeX-run-discard-foreground.
I put the patch from Ikumi-San at the end of email.

I feel good at Ikumi-San's change.

That's good news to me because such an old system still lives ;)

I understand.
Forgive me that I havn't proposed on the list.
