See 15108de2 (Merge branch 'jk/format-patch-ignore-noprefix',
2023-03-21).

An aside but `format.noprefix` is not a boolean like `diff.noprefix`.
It will be enabled with any value.

Is it standard to indicate this with the existing “If set,”, perhaps? Or
should it say “enabled with any value”?

(+Cc Peff)

    format.noprefix::
            If set, do not show any source or destination prefix in patches.
            This is equivalent to the `diff.noprefix` option used by `git
            diff` (but which is not respected by `format-patch`). Note that
            by setting this, the receiver of any patches you generate will
            have to apply them using the `-p0` option.
