Well, git-format-patch has never understood --relative,
which I think is a sane behaviour,
hence git-format-patch will never understand --no-relative after this
patch.

Oh no, to my surprise, git-format-patch does accept --[no-]relative, now.

We don't document --relative for git-format-patch, the --relative
documentation is placed under the guard, for that matter:

Documentation/diff-options.txt 


ifndef::git-format-patch[]
-R::
        Swap two inputs; that is, show differences from index or
        on-disk file to tree contents.

--relative[=<path>]::
        When run from a subdirectory of the project, it can be
        told to exclude changes outside the directory and show
        pathnames relative to it with this option.  When you are
        not in a subdirectory (e.g. in a bare repository), you
        can name which subdirectory to make the output relative
        to by giving a <path> as an argument.
endif::git-format-patch[]

Maybe time to fix the documentation.
