This is a follow up to #3: filling in the blanks from https://git-annex.branchable.com/tips/setup_a_public_repository_on_a_web_site/, I thought that only `git annex get` worked with http remotes. But now I think that was premature. Investigate and make `git-annex` uploading work over http remotes. Specifically this means these commands should work: * `git annex sync --content` * `git annex copy --to origin`
