Hello again, Thank you for integrating the patch!
Regarding licensing, I don't have immediate plans to contribute more patches to GNU (kind of swamped with things going on), but it's always a possibility. I'm happy to fill out a copyright grant to irrevocably assign ownership of my patches sent to GNU projects to FSF and/or GNU, which I assume is what that entails: just let me know. Sorry for overlooking that those earlier cases were supposed to fall through; that was sloppy of me. I tested --retry-on-host-error with and without --tries 3. With --tries 3 it stopped after 3 tries; without --tries 3 it kept going. Is there other support that is needed, or something that I'm overlooking? Thank you! —Elliot
