This is conceptually very simple, just making a 1 that was hard coded be exposed as a config option. The hard part was plumbing all that, and dealing with complexities like reading it from git attributes at the same time that numcopies is read. Behavior change: When numcopies is set to 0, git-annex used to drop content without requiring any copies. Now to get that (highly unsafe) behavior, mincopies also needs to be set to 0. It seemed better to remove that edge case, than complicate mincopies by ignoring it when numcopies is 0. This commit was sponsored by Denis Dzyubenko on Patreon.
