Yes, I am not proud of this idea. But it is simple.

I don't think we should construct an argv if !ispipe, but this is minor.
The patch should be simple anyway. Just I do not want to touch this code ;)
and to complicate it more. and create another (2nd) case when when we need
to construct argv by hand.

Oh, I will be really happy to leave this this code alone and do nothing ;)

except format_corename() has another bug, it can leak ->corename but this
is another story (I'll send the patch).
