[bug#70494] [PATCH 18/23] guix: http-client: Add network-error?.

["Ludovic Courtès" <ludo@gnu.org>]

Christopher Baines <mail@cbaines.net> skribis:

> Plus remove http-get-error? from network-error? as a http-get-error? doesn't
> indicate a network error.
>
> * guix/scripts/substitute.scm (system-error?, network-error?): Move from here.
> (process-substitution/fallback, process-substitution): Use http-get-error?
> with network-error?.
> * guix/http-client.scm: To here, and also don't use http-get-error?.
>

These two hunks should probably go to a different commit, because
they’re really fixing a bug.

(The commit log subject line doesn’t need the “guix:” prefix.)
