As discovered by Albin Söderqvist (see the commentary in his 'openttd'
patch [1]), the following command fails:
guix download
http://binaries.openttd.org/releases/1.6.0/openttd-1.6.0-source.tar.xz
with the following error:
--8<---cut here---start->8---
Starting download of /tmp/guix-file.sYMDJZ
>From http://binaries.openttd.org/releases/1.6.0/openttd-1.6.0-source.tar.xz...
ERROR: download failed
"http://binaries.openttd.org/releases/1.6.0/openttd-1.6.0-source.tar.xz"; 307
"Temporary Redirect"
failed to download "/tmp/guix-file.sYMDJZ" from
"http://binaries.openttd.org/releases/1.6.0/openttd-1.6.0-source.tar.xz";
guix download: error:
http://binaries.openttd.org/releases/1.6.0/openttd-1.6.0-source.tar.xz:

--8<---cut here---end--->8---
This happens because 'http-fetch' procedure from (guix build download)
module handles only 301 and 302 codes, while here we have 307 [2] [3].
The attached patch fixes this problem.
