Yes, looking at the code it makes sense.

In this part the only difference is a spawn of cmd /c, but I don't see
why it is useful to spawn a new command prompt here for this case, so
we could just drop this part. Looking at the log history, this has
been added since this code creation..

It would be good to get that backpatched, that's something we really
miss now IMO. Now it modifies libpgcommon, so Windows packagers (me
being one) will certainly need to patch a bit stuff but that's a
one-line changer so it's not a big deal. And I imagine that this is
actually the reason why Asif reported that as a bug as well.
