[bug#28262] [PATCH] Handle the same HTTP redirects everywhere.

[ludo@gnu.org (Ludovic Courtès)]

Hey Tobias,

Tobias Geerinckx-Rice <me@tobias.gr> skribis:

Actually guix/build/download.scm.

Good catch, go for it!

As a followup, we should look into merging the two ‘http-fetch’
procedures.  I don’t think the initial motivation for having two
separate implementations still holds.

Thanks,
