Do you mean to embed it in the commit log trailer and upon seeing it, the log family of commands add it to their setup_revisions() invocation, thusly affecting things like "format-patch" and "show"? As a reminder for a patch submitter (i.e., communicated by you who wrote the commit to future you who will run format-patch for submission), something locally maintained might be sufficient, e.g. refs/notes/diffopts that is not shared by default, but still, this hint probably wants to be per-path (ideally per-hunk). But I think it will make it annoying if you forced those who fetched from you to use "-U10" when they do "git show", as the choice would be strongly affected by personal preference. And I certainly do not want to see anything less benign than "-U10" silently forced upon me. Thanks.
