clone: Fetch the upstream remote specified in `debian/upstream/metadata`
This avoids a step if the workflow involves using --upstream-vcs-tag.
Overridable with the --upstream-remote configuration option. Set this to the empty string to disable cloning.
Shouldn't we also make import-orig (when not using a git ref) to automatically fetch the tag from the upstream remote if not available yet?
That sounds like a good idea! I might get to work on that but if I don’t get to it in time the lack of that shouldn’t block this PR hopefully (it could be a followup).
Thanks! This looks useful, we just need to get the defaults/options right.
This would still be great to have in case you want to give it a respin @iainlane
