I would like git annex sync to only sync git-annex's bookkeeping metadata, and not my master branch or file content.

I tried setting annex.synconlyannex = true (in ~/.gitconfig), and was surprised to find that although that disables syncing of my master branch, it enables syncing of content.

I can add --no-content on the command line, but I'd rather not type that every time. Is there a way to do it purely through ~/.gitconfig? (Maybe consider it as a feature request?)

(Motivation: I find it jarring when git annex creates git commits on my own branches without asking me. I already set annex.autocommit = false, but git annex sync will still make merge commits unless I set annexsynconlyannex = true.)
