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.
