Subject: [bug#37587] [PATCH 2/2] inferior: Set the error port when using older Guix versions.

From: Christopher Baines <[email-masked]>
Date: Wed, 2 Oct 2019 19:28:16 +0100

This makes the behaviour more consistent.

* guix/inferior.scm (inferior-pipe): Wrap the second open-pipe* call with
with-error-to-port, to match the first call to open-pipe*.
